Spectra of Atoms and Molecules is a very thorough and pedagogically organized textbook. It emphasizes the fundamental principles of spectroscopy with its primary goal being to teach students how to interpret spectra. The book reviews the basic skills needed to understand the material, including a clear presentation of group theory. A large number of excellent problems, many stated in the language of matrices, are found at the end of each chapter. In keeping with the visual aspects of the course, the author provides a large number of diagrams and spectra specifically recorded for this book. The author discusses such topics as molecular symmetry, matrix representation of groups, quantum mechanics and group theory. Analyses are made of atomic, rotational, vibrational, and electronic spectra. The Raman effect is also discussed. Undergraduate senior and first-year graduate students studying molecular spectroscopy will find this text indispensable. It will also be of interest to professionals in chemistry, physics, astronomy, and engineering.
