Written for beginning graduate students and advanced undergraduates, this unique text combines both introductory and modern quantum chemistry in a single volume. Unlike similar texts, which concentrate on quantum physics and provide only brief examples of chemical applications, QuantumMechanics in Chemistry focuses on the topics a chemist needs to know. It provides an introduction to the fundamentals of quantum mechanics as they apply to chemistry, then moves on to the more modern aspects of the field, which are very important in industry and are not emphasized in any other text.It also includes introductions to molecular spectroscopy, chemical dynamics, and computational chemistry as applied to electronic structures. The authors' websites offer text-related computer programs and a large number of exercises, problems, and solutions to further enhance the flexibility andutility value of the text for students, instructors, and professionals in the field. The publisher's website is linked to the authors' websites: see Appendix H for WWW addresses.
