METHODS OF MOLECULAR QUANTUM MECHANICS  by R. MCWEENY & B. T. SUTCLIFFE ___________________________________________________________ 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)  Please check pictures and don't hesitate to ask if you have any queries!   42
