Book Synopsis Theory of Orientation and Stereoselection by : K. Fukui
Download or read book Theory of Orientation and Stereoselection written by K. Fukui and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many organic chemists will agree with me that the old "electronic theory" has for a long time been inadequate for the interpretation of various new findings in chemistry, particularly for those of reactivity. Considering the outstanding progress which has been made during the past 20 years in the interpretation of these facts, aided by the molecular orbital theory, the time has finally come for a new book showing what is within and what is beyond the reach of quantum-chemical methods. It was therefore highly suitable that Dr. F. L. Boschke of the Springer Verlag suggested to me to make a contribution to a volume in the series "Topics in Current Chemistry" in February 1969. The article was published as Vol. 15, No 1 in June 1970. This new book is an expanded version of the article written in 1970. In this present volume several of the most up-to-date findings which have been gained in organic chemistry since then have been added. It is highly probable that a certain "theoretical" design in the experimenta lists' mind may have been the reason for these developments, whether they themselves are aware of it or not. Theory produces new experimental ideas and conversely, a host of experimental data add another vista to new theories. Due to the mutual beneficial effect of theory and experiment this book will always retain its value, although the quantum-chemical approach to the theory of reactivity is, of course, still in the develop mental stage.

Book Synopsis Perspectives in Electronic Structure Theory by : Roman F. Nalewajski
Download or read book Perspectives in Electronic Structure Theory written by Roman F. Nalewajski and published by Springer Science & Business Media. This book was released on 2012-03-26 with total page 727 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding in science implies insights from several different points of view. Alternative modern outlooks on electronic structure of atoms and molecules, all rooted in quantum mechanics, are presented in a single text. Together these complementary perspectives provide a deeper understanding of the localization of electrons and bonds, the origins of chemical interaction and reactivity behavior, the interaction between the geometric and electronic structure of molecules, etc. In the opening two parts the basic principles and techniques of the contemporary computational and conceptual quantum chemistry are presented, within both the wave-function and electron-density theories. This background material is followed by a discussion of chemical concepts, including stages of the bond-formation processes, chemical valence and bond-multiplicity indices, the hardness/softness descriptors of molecules and reactants, and general chemical reactivity/stability principles. The insights from Information Theory, the basic elements of which are briefly introduced, including the entropic origins and Orbital Communication Theory of the chemical bond, are the subject of Part IV. The importance of the non-additive (interference) information tools in exploring patterns of chemical bonds and their covalent and ionic components will be emphasized.

Book Synopsis Charge Sensitivity Approach To Electronic Structure And Chemical Reactivity by : Jacek Korchowiec
Download or read book Charge Sensitivity Approach To Electronic Structure And Chemical Reactivity written by Jacek Korchowiec and published by World Scientific. This book was released on 1997-01-03 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charge Sensitivity Analysis (CSA) represents a linear response treatment of molecular systems, based upon the chemical potential and hardness/softness concepts established within density functional theory (DFT). Recently, it has been shown to provide an attractive framework leading to novel approaches to chemical reactivity of open systems. The monograph presents the conceptual and methodological basis of the CSA covering its DFT roots, alternative resolutions and representations, sensitivities of closed and open atomic and molecular systems, charge stability criteria and relaxational effects due to the system environment, and alternative collective modes of charge redistribution. The CSA interaction energy in donor-acceptor systems is investigated in the second-order approximation. In particular, the relaxational contributions to the chemical potential, hardness and softness quantities are examined and their physical implications are summarized. The charge sensitivity concepts for reactive systems include: one- and two-reactant reactivity criteria, mapping relations between equilibrium displacements in the electron population and nuclear position spaces, the intersecting state model of charge transfer processes, intermediate hardness decoupling modes and the minimum energy coordinates, all defined in the electron population space. The conceptual developments are illustrated using recent qualitative and quantitative results on selected molecules, catalytic clusters and chemisorption systems. The CSA description is shown to connect directly to intuitive concepts and rules of chemistry, e.g., those related to interactions between hard/soft acids and bases.

Book Synopsis Computational Inorganic and Bioinorganic Chemistry by : Edward I. Solomon
Download or read book Computational Inorganic and Bioinorganic Chemistry written by Edward I. Solomon and published by John Wiley & Sons. This book was released on 2013-02-19 with total page 980 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades there have been major advances in our ability to computationally evaluate the electronic structure of inorganic molecules, particularly transition metal systems. This advancement is due to the Moore’s Law increase in computing power as well as the impact of density functional theory (DFT) and its implementation in commercial and freeware programs for quantum chemical calculations. Improved pure and hybrid density functionals are allowing DFT calculations with accuracy comparable to high-level Hartree-Fock treatments, and the results of these calculations can now be evaluated by experiment. When calculations are correlated to, and supported by, experimental data they can provide fundamental insight into electronic structure and its contributions to physical properties and chemical reactivity. This interplay continues to expand and contributes to both improved value of experimental results and improved accuracy of computational predictions. The purpose of this EIC Book is to provide state-of-the-art presentations of quantum mechanical and related methods and their applications, written by many of the leaders in the field. Part 1 of this volume focuses on methods, their background and implementation, and their use in describing bonding properties, energies, transition states and spectroscopic features. Part 2 focuses on applications in bioinorganic chemistry and Part 3 discusses inorganic chemistry, where electronic structure calculations have already had a major impact. This addition to the EIC Book series is of significant value to both experimentalists and theoreticians, and we anticipate that it will stimulate both further development of the methodology and its applications in the many interdisciplinary fields that comprise modern inorganic and bioinorganic chemistry. This volume is also available as part of Encyclopedia of Inorganic Chemistry, 5 Volume Set. This set combines all volumes published as EIC Books from 2007 to 2010, representing areas of key developments in the field of inorganic chemistry published in the Encyclopedia of Inorganic Chemistry.

Book Synopsis Thinking Like a Physical Organic Chemist by : Steven M. Bachrach
Download or read book Thinking Like a Physical Organic Chemist written by Steven M. Bachrach and published by Oxford University Press. This book was released on 2023 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical organic chemistry is a modern scientific subdiscipline whose reach is pervasive throughout chemistry, underpinning every academic and industrial synthetic process. All current organic chemistry textbooks rest upon the foundations of physical organic chemistry, and all of them rely on the concept of reaction mechanism as the means for understanding organic reactions. Yet many outside of the discipline either fear the topic or know nothing about it at all. The perceived difficulty of the subject of organic chemistry often prevents consideration of how the methods of organic chemists, their process of asking questions, devising tests, and building models, can be translated into other disciplines. In Thinking Like a Physical Organic Chemist, Professor Steven M. Bachrach uses analogies and colorful examples to provide experts and nonexperts alike with an alternative way of thinking about organic chemistry. He highlights a number of reaction mechanisms, walking through the important experiments that they rest upon, with an emphasis on the rules and logic systems that organic chemists have built to understand and predict reaction outcomes.
