Fundamentals of Molecular Spectroscopy

A concise introduction to the spectroscopy of atoms and molecules is provided in this book. The treatment emphasizes an intuitive understanding of topics and the development of problem-solving techniques. Background material on time-dependent perturbation theory and second quantization is provided, and many illustrative spectra from the literature are included. The author examines electronic band spectra and polyatomic rotations, which make accessible the energy levels and selection rules that govern microwave spectroscopy without recourse to detailed rotational eigenstates. Also covered are triatomic molecules, aromatic hydrocarbons, lasers, multiphoton spectroscopies, and diagrammatic perturbation techniques.
