The last twenty years have seen remarkable advances in molecular quantum mechanics. The traditional methods expounded in the first successful edition of this book have been implemented on a grand scale. In the Second Edition, McWeeny has completely revised the text and has added a wealth of new material and example problems. Key Features * Self-contained development of modern quantum theory of molecular electronic structure and properties * Assumes only an elementary quantum mechanics background * Mathematical methods (vector spaces, representations, group theory, etc.) built up as required * Latest advances (use of second quantization, unitary group, propagators all developed assuming no previous knowledge)

Since this book was first published 20 years ago, there have been remarkable advances in molecular quantum mechanics. The traditional methods expounded in the first edition have been absorbed into thegrowing field of "computational chemistry": but the whole fabric of the subject has also changed under the impact of techniques originating in theoretical physics. Consequently, besides rewriting much of the original text, it has been necessary to add an almost equal amount of completely new material: this covers second quantization and diagrammatic perturbation theory,symmetric and unitary group methods, new forms of valence bond theory, dynamic properties and response, propagator and equation-of-motiontechniques and the theory of intermolecular forces. Problems (withhints on solutions) appear at the end of each chapter and form a valuable supplement to the text. Like the first edition, this is a "teaching book" which follows a deductive step-by-step path from basic principles up to the current frontiers of research. Although aimed primarily at graduate students and their teachers, it should be standard reference for all who come in contact with modern theories of the electronic structure and properties of molecules. The last twenty years have seen remarkable advances in molecular quantum mechanics. The traditional methods expounded in the first successful edition of this book have been implemented on a grand scale. In the Second Edition, Mcweeny has completly revised the text and has added a wealth of new material and example problems.

Advances in Quantum Chemistry presents surveys of current developments in this rapidly developing field that falls between the historically established areas of mathematics, physics, chemistry, and biology. With invited reviews written by leading international researchers, each presenting new results, it provides a single vehicle for following progress in this interdisciplinary area. Theoretical methods have dramatically extended the reach and grasp of atmospheric scientists. This edition of Advances in Quantum Chemistry collects a broad range of articles that provide reports from the leading edge of this interaction. The chemical systems span the range from atoms to clusters to droplets. Electronic structure calculations are used to uncover the details of the breakdown and removal of emissions from the atmosphere and the simultaneous development of air pollution including ozone and particles. The anomalous enrichment of heavy isotopes in atmospheric ozone is discussed using RRKM theory, and a number of techniques are presented for calculating the effect of isotopic substitution on the absorption spectra of atmospheric molecules. * Publishes articles, invited reviews and proceedings of major international conferences and workshops * Written by leading international researchers in quantum and theoretical chemistry * Highlights important interdisciplinary developments

Second Quantization-Based Methods in Quantum Chemistry presents several modern quantum chemical tools that are being applied to electronic states of atoms and molecules. Organized into six chapters, the book emphasizes the quantum chemical methods whose developments and implementations have been presented in the language of second quantization. The opening chapter of the book examines the representation of the electronic Hamiltonian, other quantum-mechanical operators, and state vectors in the second-quantization language. This chapter also describes the unitary transformations among orthonormal orbitals in an especially convenient manner. In subsequent chapters, various tools of second quantization are used to describe many approximation techniques, such as Hartree-Fock, perturbation theory, configuration interaction, multiconfigurational Hartree-Fock, cluster methods, and Green’s function. This book is an invaluable source for researchers in quantum chemistry and for graduate-level students who have already taken introductory courses that cover the fundamentals of quantum mechanics through the Hartree-Fock method as applied to atoms and molecules.

An introduction to the rapidly evolving methodology of electronic excited states For academic researchers, postdocs, graduate and undergraduate students, Quantum Chemistry and Dynamics of Excited States: Methods and Applications reports the most updated and accurate theoretical techniques to treat electronic excited states. From methods to deal with stationary calculations through time-dependent simulations of molecular systems, this book serves as a guide for beginners in the field and knowledge seekers alike. Taking into account the most recent theory developments and representative applications, it also covers the often-overlooked gap between theoretical and computational chemistry. An excellent reference for both researchers and students, Excited States provides essential knowledge on quantum chemistry, an in-depth overview of the latest developments, and theoretical techniques around the properties and nonadiabatic dynamics of chemical systems. Readers will learn: ● Essential theoretical techniques to describe the properties and dynamics of chemical systems ● Electronic Structure methods for stationary calculations ● Methods for electronic excited states from both a quantum chemical and time-dependent point of view ● A breakdown of the most recent developments in the past 30 years For those searching for a better understanding of excited states as they relate to chemistry, biochemistry, industrial chemistry, and beyond, Quantum Chemistry and Dynamics of Excited States provides a solid education in the necessary foundations and important theories of excited states in photochemistry and ultrafast phenomena.

This book is intended for physicists and chemists who need to understand the theory of atomic and molecular structure and processes, and who wish to apply the theory to practical problems. As far as practicable, the book provides a self-contained account of the theory of relativistic atomic and molecular structure, based on the accepted formalism of bound-state Quantum Electrodynamics. The author was elected a Fellow of the Royal Society of London in 1992.
