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)
