A supplemental text for either a junior-/senior-level course in quantum chemistry and spectroscopy or the first half of a second semester physical chemistry sequence, which begins with quantum chemistry. One year of basic calculus required. Dykstra offers a concise, up-to-date, and non-intimidating introduction to one of the most challenging subjects of undergraduate chemistry majors. His presentation of formal elements of quantum theory and the analysis for specific problems in infrared spectroscopy, electronic structure, and magnetic resonance is both readable and rigorous.
