Book Synopsis Polymorphism in Molecular Crystals by : Joel Bernstein
Download or read book Polymorphism in Molecular Crystals written by Joel Bernstein and published by Oxford University Press. This book was released on 2002 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymorphism - the multiplicity of structures or forms - is a term that is used in many disciplines. In chemistry it refers to the existence of more than one crystal structure for a particular chemical substance. The properties of a substance are determined by its composition and by its structure. In the last two decades, there has been a sharp rise in the interest in polymorphic systems, as an intrinsically interesting phenomenon and as an increasingly important component in the development and marketing of a variety of materials based on organic molecules (e.g. pharmaceuticals, dyes and pigments, explosives, etc.). This book summarizes and brings up to date the current knowledge and understanding of polymorphism of molecular crystals, and concentrates it in one comprehensive source. The book will be an invaluable reference for students, researchers, and professionals in the field.

Book Synopsis Organic Molecular Crystals by : E. Silin̦š
Download or read book Organic Molecular Crystals written by E. Silin̦š and published by American Institute of Physics. This book was released on 1994 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Market: Specialists, researchers, and students in solid-state physics, materials science, electronics, chemical physics, organic and physical chemistry, and molecular biophysics. This monograph focuses on the interaction processes of excitons and charge carriers with the local environment, including the polarization and localization phenomena and the formation of polaronic quasi- particles. Transport phenomena are discussed and directly correlated with interaction dynamics, which actually determine the time- and temperature-dependent transiton of charge carriers and excitons from a coherent to a diffusive mode of motion.
Book Synopsis The Atom-Atom Potential Method by : Alexander J. Pertsin
Download or read book The Atom-Atom Potential Method written by Alexander J. Pertsin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of physics furnishes many examples of how a simple semiem pirical method, essentially based on intuitive considerations, may prove to be much more successful than a rigorous theoretical approach. A pertinent example is the method of atom-atom potentials, which treats the intermolec ular interactions between polyatomic molecules in terms of pairwise inter actions between their constituent atoms. Despite a few conceptual short comings, the method provides a fairly reliable practical means of handling, on a microscopic level, a wide range of problems that arise in the solid-state physics and chemistry of organic compounds. This monograph is an attempt to generalize the experience gained in the past twenty years in interpreting the static and dynamic properties of organic molecular solids in terms of atom-atom potentials. It embraces nearly all aspects of the application of the method, including an evaluation of cohesive energies, equilibrium crystal structures, phonon spectra, ther modynamic functions, and crystal defects. Many related topics such as the effect of the crystal field on molecular conformation, the determination of crystal structures from raw diffraction data, and the problem of polymor phic transitions are also discussed. We believe that this book will be of use to researchers in solid-state physics, chemistry, crystallography, physical chemistry, and polymer chem istry. It also gives us an opportunity to acknowledge our indebtedness to those who sent us published as well as unpublished information and sugges tions, including A.T. Amos, E.L. Bokhenkov, H. Bonadeo, R.K. Boyd, C.P.
Book Synopsis Photophysics of Molecular Materials by : Guglielmo Lanzani
Download or read book Photophysics of Molecular Materials written by Guglielmo Lanzani and published by John Wiley & Sons. This book was released on 2006-05-12 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon based pi-conjugated materials offer a broad range of applications, going from molecular electronics and single molecule devices to nanotechnology, plastic electronics and optoelectronics. The proper physical description of such materials is in between that of molecular solids and that of low-dimensional covalent semiconductors. This book is a comprehensive review of their elementary excitations processes and dynamics, which merges the two viewpoints, sometimes very different if not contrasting. In each chapter, a broad tutorial introduction provides a solid physical background to the topic, which is further discussed based on recent experimental results obtained via state-of-the-art techniques. Both the molecular, intra-chain character and the solid state, inter-molecular physics is addressed. Reports on single molecule and single polymer chain spectroscopy introduce the on-site phenomena. Several chapters are dedicated to nano-probes, steady state and transient spectroscopies. The highly ordered state, occurring in single crystals, is also discussed thoroughly. Finally, less conventional tools such as THz spectroscopy are discussed in detail. The book provides a useful introduction to the field for newcomers, and a valid reference for experienced researchers in the field.

Book Synopsis Engineering Crystallography: From Molecule to Crystal to Functional Form by : Kevin J. Roberts
Download or read book Engineering Crystallography: From Molecule to Crystal to Functional Form written by Kevin J. Roberts and published by Springer. This book was released on 2017-07-18 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the current state-of-the-art regarding the application of applied crystallographic methodologies for understanding, predicting and controlling the transformation from the molecular to crystalline state with the latter exhibiting pre-defined properties. This philosophy is built around the fundamental principles underpinning the three inter-connected themes of Form (what), Formation (how) and Function (why). Topics covered include: molecular and crystal structure, chirality and ferromagnetism, supramolecular assembly, defects and reactivity, morphology and surface energetics. Approaches for preparing crystals and nano-crystals with novel physical, chemical and mechanical properties include: crystallisation, seeding, phase diagrams, polymorphic control, chiral separation, ultrasonic techniques and mechano-chemistry. The vision is realised through examination of a range of advanced analytical characterisation techniques including in-situ studies. The work is underpinned through an unprecedented structural perspective of molecular features, solid-state packing arrangements and surface energetics as well as in-situ studies. This work will be of interest to researchers, industrialists, intellectual property specialists and policy makers interested in the latest developments in the design and supply of advanced high added-value organic solid-form materials and product composites.
Book Synopsis Optical Spectra and Lattice Dynamics of Molecular Crystals by : G.N. Zhizhin
Download or read book Optical Spectra and Lattice Dynamics of Molecular Crystals written by G.N. Zhizhin and published by Elsevier. This book was released on 1995-10-17 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current volume is a single topic volume on the optical spectra and lattice dynamics of molecular crystals. The book is divided into two parts. Part I covers both the theoretical and experimental investigations of organic crystals. Part II deals with the investigation of the structure, phase transitions and reorientational motion of molecules in organic crystals.In addition appendices are given which provide the parameters for the calculation of the lattice dynamics of molecular crystals, procedures for the calculation of frequency eigenvectors of utilizing computers, and the frequencies and eigenvectors of lattice modes for several organic crystals. Quite a large amount of Russian literature is cited, some of which has previously not been available to scientists in the West.
Book Synopsis Crystalline Molecular Complexes and Compounds by : Frank H. Herbstein
Download or read book Crystalline Molecular Complexes and Compounds written by Frank H. Herbstein and published by OUP Oxford. This book was released on 2005-11-17 with total page 1352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and unified account of the structure and properties of crystalline binary adducts. Perhaps better known as molecular complexes and compounds, these crystals are currently estimated (from molecular recognition studies) to make up one quarter of the world's crystals, providing evidence for some sort of special attraction between the two components. DNA is perhaps the most famous example but others (hydrates, solvates, host-guest inclusion complexes, donor-acceptor compounds) pervade the whole body of solid state chemistry. Although much research has been published, there has never been a comprehensive and unified treatment of the whole field. This book has been designed to fill this gap, comparing and contrasting the various examples and the different types of interaction (hydrogen bonding, inclusion and localized or delocalized charge transfer). More than 600 figures, 200 tables and 3500 references are included in the book. Since most 'parent compounds' form a number of adducts, the fraction of crystalline binary adducts is only going to grow making this account just the 'tip of the iceberg'.

The topics discussed in the 28 contributions in this book provide a state-of-the-art description of the field and offer new research ideas that, if pursued, will serve to strengthen the field at the interface between supramolecular chemistry and materials science.
Book Synopsis Intermolecular Interactions in Crystals by : Juan J Novoa
Download or read book Intermolecular Interactions in Crystals written by Juan J Novoa and published by Royal Society of Chemistry. This book was released on 2017-10-25 with total page 782 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of crystal engineering concerns the design and synthesis of molecular crystals with desired properties. This requires an in-depth understanding of the intermolecular interactions within crystal structures. This new book brings together the latest information and theories about intermolecular bonding, providing an introductory text for graduates. The book is divided into three parts. The first part covers the nature, physical meaning and methods for identification and analysis of intermolecular bonds. The second part explains the different types of bond known to occur in molecular crystals, with each chapter written by a specialist in that specific bond type. The final part discusses the cooperativity effects of different bond types present in one solid. This comprehensive textbook will provide a valuable resource for all students and researchers in the field of crystallography, materials science and supramolecular chemistry.
Book Synopsis Thermophysical Properties of Materials by : G. Grimvall
Download or read book Thermophysical Properties of Materials written by G. Grimvall and published by Elsevier. This book was released on 1999-09-22 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a thoroughly revised version of the original book published in 1986. About half of the contents of the previous version remain essentially unchanged, and one quarter has been rewritten and updated. The rest consists of completely new and extended material. Recent research has focussed on new materials made through "molecular engineering", and computational materials science through ab initio electron structure calculations. Another trend is the ever growing interdisciplinary aspect of both basic and applied materials science. There is an obvious need for reviews that link well established results to the modern approaches. One purpose of this book is to provide such an overview in a specific field of materials science, namely thermophysical phenomena that are intimately connected with the lattice vibrations of solids. This includes, e.g., elastic properties and electrical and thermal transport. Furthermore, this book attempts to present the results in such a form that the reader can clearly see their domain of applicability, for instance if and how they depend on crystal structure, defects, applied pressure, crystal anisotropy etc. The level and presentation is such that the results can be immediately used in research. Graduate students in condensed matter physics, metallurgy, inorganic chemistry or geophysical materials will benefit from this book as will theoretical physicists and scientists in industrial research laboratories.
Book Synopsis Nonlinear Optical Properties of Organic Molecules and Crystals V1 by : D.S. Chemla
Download or read book Nonlinear Optical Properties of Organic Molecules and Crystals V1 written by D.S. Chemla and published by Elsevier. This book was released on 2012-12-02 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear Optical Properties of Organic Molecules and Crystals, Volume 1 discusses the nonlinear optical effects in organic molecules and crystals, providing a classical distinction between quadratic and cubic processes. This book begins with a general overview of the basic properties of organic matter, followed by a review on the benefits derived from quantum-chemistry-based models and growth and characterization of high quality, bulk organic crystals and waveguided structures. A case study focusing on a specific material, namely urea, which exemplifies a situation in which transparency in the UV region has been purposely traded for nonlinear efficiency is also deliberated. This text concludes with a description of a type of trade-off between the unpredictable orientation of molecules in crystalline media, polarity of liquid-crystalline structures, and dominant electronic contribution to the electro-optic effect. This publication is beneficial to solid-state physicists and chemists concerned with nonlinear optical properties of organic molecules and crystals.
Book Synopsis Vibronic Interactions in Molecules and Crystals by : Isaac B. Bersuker
Download or read book Vibronic Interactions in Molecules and Crystals written by Isaac B. Bersuker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibronic interaction effects constitute a new field of investigation in the physics and chemistry of molecules and crystals that combines all the phenomena and laws originating from the mixing of different electronic states by nuclear displacements. This field is based on a new concept which goes beyond the separate descriptions of electronic and nuclear motions in the adiabatic approximation. Publications on this topic often appear under the title of the lahn-Thller effect, although the area of application of the new approach is much wider: the term vibronic interaction seems to be more appropriate to the field as a whole. The present understanding of the subject was reached only recently, during the last quarter of a century. As a result of intensive development of the theory and experiment, it was shown that the nonadiabatic mixing of close-in-energy elec tronic states under nuclear displacements and the back influence of the modified electronic structure on the nuclear dynamics result in a series of new effects in the properties of molecules and crystals. The applications of the theory of vibronic in of spectroscopy [including visible, ultraviolet, in teractions cover the full range frared, Raman, EPR, NMR, nuclear quadrupole resonance (NQR), nuclear gam ma resonance (NOR), photoelectron and x-ray spectroscopy], polarizability and magnetic susceptibility, scattering phenomena, ideal and impurity crystal physics and chemistry (including structural as well as ferroelectric phase transitions), stereochemistry and instability of molecular (including biological) systems, mechanisms of chemical reactions and catalysis.
Book Synopsis Chemical Physics of Molecular Condensed Matter by : Kazuya Saito
Download or read book Chemical Physics of Molecular Condensed Matter written by Kazuya Saito and published by Springer Nature. This book was released on 2020-10-09 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book fills a gap in knowledge between chemistry- and physics-trained researchers about the properties of macroscopic (bulk) material. Although many good textbooks are available on solid-state (or condensed matter) physics, they generally treat simple systems such as simple metals and crystals consisting of atoms. On the other hand, textbooks on solid-state chemistry often avoid descriptions of theoretical background even at the simplest level. This book gives coherent descriptions from intermolecular interaction up to properties of condensed matter ranging from isotropic liquids to molecular crystals. By omitting details of specific systems for which comprehensive monographs are available—on liquid crystals and molecular conductors, for instance—this book highlights the effects of molecular properties, i.e., the presence of the shape and its deformation on the structure and properties of molecular systems.
Book Synopsis The Molecular Dynamics of Liquid Crystals by : G.R. Luckhurst
Download or read book The Molecular Dynamics of Liquid Crystals written by G.R. Luckhurst and published by Springer Science & Business Media. This book was released on 1994-04-30 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid-crystalline phases are now known to be formed by an ever growing range of quite diverse materials, these include those of low molecular weight as well as the novel liquid-crystalline polymers, such phases can also be induced by the addition of a solvent to amphiphilic systems leading to lyotropic liquid crystals. Irrespective of the structure of the constituent molecules these numerous liquid-cl)'Stailine phases are characterised by their long range orientational order. In addition certain phases exhibit elements of long range positional order. Our understanding, both experimental and theoretical, at the molecular level of the static behaviour of these fascinating and important materials is now well advanced. In contrast the influence of the long range order; both orientational and positional, on the molecular dynamics in liquid Cl)'Stais is less well understood. In an attempt to address this situation a NATO Advanced Study Institute devoted to liquid ctystal dynamics was held at n Ciocco, Barga, Italy in September 1989. This brought together experimentalists and theoreticians concerned with the various dynamical processes occurring in all liquid crystals. The skills of the participants was impressively wide ranging; they spanned the experimental techniques used in the study of molecular dynamics, the nature of the systems investigated and the theoretical models employed to understand the results. While much was learnt it was also recognised that much more needed to be done in order to advance our understanding of molecular dynamics in liquid Cl)'Stais.
