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)

The first edition was published in 1969; changes in the underlying theoretical fabric of quantum chemistry, largely as a result of methods originating in theoretical physics, spurred this revision. An essentially self-contained teaching book rather than a guide to the literature, it takes the beginning graduate student in chemistry or physics up to the research frontiers.

No praise is too high for this excellent book: it presents an admirably perceptive and comprehensive account of theoretical chemsitry.

--JOURNAL OF MOLECULAR STRUCTURE

All in all, this is an excellent new version of an important textbook.

--NATURE

This is a mathematical text of the highest calibre. It is a tribute to the author that the book contains so much material in a rapidly expanding field.....Scientists in molecular quantum mechanics will wish to have this text.

--JOURNAL OF THE AMERICAN CHEMICAL SOCIETY

This is a work of scholarship summarizing a long professional lifetime in quantum chemistry.
