Book Synopsis Potential Energy Surfaces and Dynamics Calculations by : Donald Truhlar
Download or read book Potential Energy Surfaces and Dynamics Calculations written by Donald Truhlar and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume is concerned with two of the central questions of chemical dynamics. What do we know about the energies of interaction of atoms and molecules with each other and with solid surfaces? How can such interaction energies be used to understand and make quantitative predictions about dynamical processes like scattering, energy transfer, and chemical reactions? It is becoming clearly recognized that the computer is leading to rapid progress in answering these questions. The computer allows probing dynamical mechanisms in fine detail and often allows us to answer questions that cannot be addressed with current experimental techniques. As we enter the 1980's, not only are more powerful and faster computers being used, but techniques and methods have been honed to a state where exciting and reliable data are being generated on a variety of systems at an unprecedented pace. The present volume presents a collection of work that illustrates the capabilities and some of the successes of this kind of computer-assisted research. In a 1978 Chemical Society Report, Frey and Walsh pointed out that "it is extremely doubtful if a calculated energy of activation for any unimolecular decomposition can replace an experimental deter mination. " However they also recorded that they "believe[d] that some of the elaborate calculations being performed at present do suggest that we may be approaching a time when a choice between reaction mechanisms will be helped by such [computational] work.

Book Synopsis Properties of Chemically Interesting Potential Energy Surfaces by : Dietmar Heidrich
Download or read book Properties of Chemically Interesting Potential Energy Surfaces written by Dietmar Heidrich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary chemical reaction theory is the characterization of Potential Energy Hypersurfaces (PES). The authors critically analyze chemically and mathematically suitable reaction path definitions. The book presents a simple mathematical analysis of stationary and critical points of the PES. It provides tools for studying chemical reactions by calculating reaction paths and related curves. A further aspect of the book is the dependence of PES properties on approximations used for the analysis. Recent quantum chemical calculations, particularly of single proton transfer processes, and experimental data are compared. The book addresses students and researchers in Theoretical Chemistry, Chemical Kinetics and related fields.

This book was released on 2012-12-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The calculation of cross sections and rate constants for chemical reactions in the gas phase has long been a major problem in theoretical chemistry. The need for reliable and applicable theories in this field is evident when one considers the significant recent advances that have been made in developing experimental techniques, such as lasers and molecular beams, to probe the microscopic details of chemical reactions. For example, it is now becoming possible to measure cross sections for chemical reactions state selected in the vibrational rotational states of both reactants and products. Furthermore, in areas such as atmospheric, combustion and interstellar chemistry, there is an urgent need for reliable reaction rate constant data over a range of temperatures, and this information is often difficult to obtain in experiments. The classical trajectory method can be applied routinely to simple reactions, but this approach neglects important quantum mechanical effects such as tunnelling and resonances. For all these reasons, the quantum theory of reactive scattering is an area that has received considerable attention recently. This book describes the proceedings of a NATO Advanced Research Workshop held at CECAM, Orsay, France in June, 1985. The Workshop concentrated on a critical examination and discussion of the recent developments in the theory of chemical reaction dynamics, with particular emphasis on quantum theories. Several papers focus on exact theories for reactions.

Book Synopsis Computational Chemistry by : Errol G. Lewars
Download or read book Computational Chemistry written by Errol G. Lewars and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational chemistry has become extremely important in the last decade, being widely used in academic and industrial research. Yet there have been few books designed to teach the subject to nonspecialists. Computational Chemistry: Introduction to the Theory and Applications of Molecular and Quantum Mechanics is an invaluable tool for teaching and researchers alike. The book provides an overview of the field, explains the basic underlying theory at a meaningful level that is not beyond beginners, and it gives numerous comparisons of different methods with one another and with experiment. The following concepts are illustrated and their possibilities and limitations are given: - potential energy surfaces; - simple and extended Hückel methods; - ab initio, AM1 and related semiempirical methods; - density functional theory (DFT). Topics are placed in a historical context, adding interest to them and removing much of their apparently arbitrary aspect. The large number of references, to all significant topics mentioned, should make this book useful not only to undergraduates but also to graduate students and academic and industrial researchers.
Book Synopsis Potential Energy Surfaces and Molecular Dynamics of Chlorine-oxygen Systems by :
Download or read book Potential Energy Surfaces and Molecular Dynamics of Chlorine-oxygen Systems written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The theme of this thesis is the construction of analytical potential energy surfaces for small polyatomic molecules and the study of certain chlorine oxygen reactions by using the classical trajectory model. Chapter One covers the theoretical background by introducing the concept of potential energy surface, reviewing empirical methods to calculate potential energy surfaces and finally showing the classical limit of the quantum differential cross section. In chapter two a method is given to construct explicit analytical functions for triatomic molecules which have more than one minimum, either related by symmetry or not. The method is applied to ozone. In chapter three analytical potential functions are constructed for the ground states of H02, S0 2 and C102. In chapter four an explicit function has been derived for the potential energy surface of the ground state of CIO3 by using a many-body expansion. In chapter five the classical dynamics is used to study the reactions 0+CIO Cl+o2 Cl+02 CIO+o2 which are important in the upper atmosphere. Angular and energy distributions and macroscopic rate constants are calculated. The details of the atom-triatom Monte Carlo classical trajectory calculations are given in an appendix.
