Description : Concepts and Methods in Modern Theoretical Chemistry: Electronic Structure and Reactivity, the first book in a two-volume set, focuses on the structure and reactivity of systems and phenomena. A new addition to the series Atoms, Molecules, and Clusters, this book offers chapters written by experts in their fields. It enables readers to learn how concepts from ab initio quantum chemistry and density functional theory (DFT) can be used to describe, understand, and predict electronic structure and chemical reactivity. This book covers a wide range of subjects, including discussions on the following topics: DFT, particularly the functional and conceptual aspects Excited states, molecular electrostatic potentials, and intermolecular interactions General theoretical aspects and application to molecules Clusters and solids, electronic stress, and electron affinity difference The information theory and the virial theorem New periodic tables The role of the ionization potential Although most of the chapters are written at a level that is accessible to a senior graduate student, experienced researchers will also find interesting new insights in these experts’ perspectives. This comprehensive book provides an invaluable resource toward understanding the whole gamut of atoms, molecules, and clusters.
Description : Concepts and Methods in Modern Theoretical Chemistry, Two-Volume Set focuses on the structure and dynamics of systems and phenomena. A new addition to the series Atoms, Molecules, and Clusters, the two books offer chapters written by experts in their fields. They enable readers to learn how concepts from ab initio quantum chemistry, density functional theory (DFT), and molecular simulation can be used to describe, understand, and predict electronic structure, chemical reactivity, and dynamics. The first book focuses on the electronic structure and reactivity of many-electron systems, and the second book deals with the statistical mechanical treatment of collections of such systems. Concepts and Methods in Modern Theoretical Chemistry: Electronic Structure and Reactivity includes articles on DFT, particularly the functional and conceptual aspects, excited states, molecular electrostatic potentials, intermolecular interactions, general theoretical aspects, application to molecules, clusters and solids, electronic stress, the information theory, the virial theorem, new periodic tables, the role of the ionization potential, electron affinity difference, and more. Concepts and Methods in Modern Theoretical Chemistry: Statistical Mechanics includes chapters on time-dependent DFT, quantum fluid dynamics (QFD), photodynamic control, nonlinear dynamics, molecules in laser fields, charge carrier mobility, excitation energy transfer, chemical reactions, quantum Brownian motion, the third law of thermodynamics, transport properties, and nucleation. Although most of the chapters are written at a level that is accessible to a senior graduate student, experienced researchers will also find interesting new insights in these experts’ perspectives. This comprehensive set provides an invaluable guide toward understanding the whole gamut of atoms, molecules, and clusters.

Description : Unique in its comprehensive coverage of not only theoretical methods but also applications in computational spectroscopy, this ready reference and handbook compiles the developments made over the last few years, from single molecule studies to the simulation of clusters and the solid state, from organic molecules to complex inorganic systems and from basic research to commercial applications in the area of environment relevance. In so doing, it covers a multitude of apparatus-driven technologies, starting with the common and traditional spectroscopic methods, more recent developments (THz), as well as rather unusual methodologies and systems, such as the prediction of parity violation, rare gas HI complexes or theoretical spectroscopy of the transition state. With its summarized results of so many different disciplines, this timely book will be of interest to newcomers to this hot topic while equally informing experts about developments in neighboring fields.

Description : Theory and experiment in chemistry today provide a wealth of data, but such data have no meaning unless they are correctly interpreted by sound and transparent physical models. Linus Pauling was a grandmaster in the modelling of molecular properties. Indeed, many of his models have served chemistry for decades and that has been his lasting legacy for chemists all over the world. The aim of this book is to put such simple models into the language of modern quantum chemistry, thus providing a deeper justification for many of Pauling's ideas and concepts. However, it should be stressed that many contributions to this work, written by some of the world's most prominent theoretical chemists, do not merely follow Pauling's footprints. By taking his example, they made bold leaps forward to overcome the limitations of the old models, thereby opening new scientific vistas. This book is an important contribution to the chemical literature. It is an almost obligatory textbook for postgraduate students and postdoctoral researchers in physical chemistry, chemical physics and advanced physical organic chemistry.
Description : Physical Methods in Modern Chemical Analysis, Volume 3 presents the fundamental principles, the instrumentation or necessary equipment, and applications of selected physical methodologies in chemical analysis. This volume contains chapters that discuss various topics on chemical analysis methods such as transform methods in chemistry; X-ray spectrometry; the principles of electrochemical measurements; and global optimization strategy for gas-chromatographic separations. The book will prove to be an excellent reference material for chemists, researchers, and students of chemistry.
Description : This volume focuses on the use of quantum theory to understand and explain experiments in organic chemistry. High level ab initio calculations, when properly performed, are useful in making quantitative distinctions between various possible interpretations of structures, reactions and spectra. Chemical reasoning based on simpler quantum models is, however, essential to enumerating the likely possibilities. The simpler models also often suggest the type of wave function likely to be involved in ground and excited states at various points along reaction paths. This preliminary understanding is needed in order to select the appropriate higher level approach since most higher level models are designed to describe improvements to some reasonable zeroth order wave function. Consequently, most of the chapters in this volume begin with experimental facts and model functions and then progress to higher level theory only when quantitative results are required.In the first chapter, Zimmerman discusses a wide variety of thermal and photochemical reactions of organic molecules. Gronert discusses the use of ab initio calculations and experimental facts in deciphering the mechanism of ?-elimination reactions in the gas phase. Bettinger et al focus on carbene structures and reactions with comparison of the triplet and singlet states. Next, Hrovat and Borden discuss more general molecules with competitive triplet and singlet contenders for the ground state structure. Cave explains the difficulties and considerations involved with many of the methods and illustrates the difficulties by comparing with the UV spectra of short polyenes. Jordan et al discuss long-range electron transfer using model compounds and model Hamiltonians. Finally, Hiberty discusses the breathing orbital valence bond model as a different approach to introducing the crucial åã correlation that is known to be important in organic reactions.
