Description: This advanced graduate-level text explores quantum mechanical techniques from the point of view of chemistry and materials science -- emphasizing dynamics, symmetry, and formalism. Following a review of concepts from introductory quantum mechanics, the beginning chapters look at symmetry, rotations, and angular momentum addition. Chapter 4 introduces the basic formalism of time-dependent quantum mechanics, emphasizing perturbation theory and Fermi's golden rule, and chapter 5 sees this formalism applied to the interaction of radiation and matter. In chapter 6, the authors introduce occupation number representations. Chapters 7 and 8 focus on scattering theory and use its concepts to develop basic theories of chemical reaction rates. The remaining three chapters deal with the use of correlation functions and density matrices in quantum mechanics. Problems and a bibliography appear at the end of each chapter, along with an answer section new to this edition.
