The present volume contains the text of the invited lectures presented at the Symposium on Many- Body Methods in Quantum Chemistry, held on the campus of Tel Aviv University in August 1988. The Symposium was a satellite meeting of the Sixth International Congress on Quantum Chemistry held in Jerusalem. The development and application of many-body methods in Quantum chemistry have been on the rise for a number of years. This is therefore a good time for an interim report on the state of the field. It is hoped that such a report is hereby provided, though it may not be complete. The Symposium...

Provides a general approach to aspects of perturbation theory, covering all topics from the construction, analysis and summation of perturbation series to applications. Special emphasis is placed on simple methods, as well as ideas stemming from the physics of systems of interest.

The mathematical treatment of coronoid hydrocarbons is a continuation of the authors' previous book "Kekule Structures" "in Benzenoid Hydrocarbons" (Lecture Notes in Chemistry, Vol. 46). The book addresses theoretical and mathematical chemists and graduate students. The treatment includes topological properties of coronoid systems, their enumeration and classification, the number of Kekule structures and of aromatic sextets.

This monograph presents the definitions, concepts, notions and methodologies of both spatial and temporal fractals. Simple examples and illustrations are used to illustrate the text, and all concepts are applied to various scientific and engineering problems.

The presence of freely moving charges gives peculiar properties to electrolyte solutions, such as electric conductance, charge transfer, and junction potentials in electrochemical systems. These charges play a dominant role in transport processes, by contrast with classical equilibrium thermodynamics which considers the electrically neutral electrolyte compounds. The present status of transport theory does not permit a first prin- ciples analys1s of all transport phenomena with a detailed model of the relevant interactions. Host of the models are still unsufficient for real systems of...

"Quantum Chemistry" is the course material of a European Summer School in Quantum Chemistry, organized by Bj-rn O. Roos. It consists of lectures by outstanding scientists who participate in the education of students and young scientists. The book has a wider appeal as additional reading for University courses. Contents: P.-A. Malmquist: Mathematical Tools in Quantum Chemistry J. Olsen: The Method of Second Quantization P.R. Taylor: Molecular Symmetry and Quantum Chemistry B.O. Roos: The Multiconfigurational (MC) Self-Consistent Field (SCF) Theory P.E.M. Siegbahn: The Configuration Interaction...

This work offers a formulation for the prediction of the energy levels of many-electron atomic systems within the framework of a configuration interaction treatment, with consideration of the most important relativistic corrections as well as the interaction with magnetic fields.

A reference work which lists calculations related to the relativistic effects of the properties of the heavier atoms and molecules. The material is organized by subject into tables, each containing concise characterizations.

This book presents a computational scheme for calculating the electronic properties of crystalline systems at an ab-ini tio Hartree-Fock level of approximation. The first chapter is devoted to discussing in general terms the limits and capabilities of this approximation in solid state studies, and to examining the various options that are open for its implementation. The second chapter illustrates in detail the algorithms adopted in one specific computer program, CRYSTAL, to be submitted to QCPE. Special care is given to illustrating the role and in: fluence of computational parameters,...

In this book a presentation of a phenomenological theory of elec- trochemistry is given. More precisely, it should be stated that only one part of the whole field of electrochemistry is developed. It is the purpose of this treatment to describe the interconnection between the electric current in a composite thermodynamic system and the rate of production of a certain substance on the one side, the rate of deple- tion of another substance on the other side, and the work per unit time which has to be delivered to or is supplied by the system. The last part of this programme leads to the...
