The richly illustrated, advanced textbook comprehensively explains the important principles of diatomic and polyatomic molecules and their spectra in two distinct parts. The first concentrates on the theoretical aspects of molecular physics, such as the vibration, rotation, electronic states, potential curves, and spectra of molecules, while also covering the different methods of approximation for the calculation of electronic wave functions and their energy. The introduction of basic terms used in group theory and their meaning in molecular physics enables an elegant description of polyatomic molecules and their symmetries. A whole chapter is devoted to molecular spectra and the dynamic processes involved in their excited states. The theoretical section concludes with a discussion of the field of Van der Waals molecules and clusters.

The second part is devoted entirely to experimental techniques, such as laser, Fourier, NMR, and ESR spectroscopies, used in the fields of physics, chemistry, biology, and material science. Time–resolved measurements and the influence of chemical reactions by coherent controls are also treated, and a list of general textbooks and specialized literature is provided for further reading.

With its specific examples, definitions, and integrated notes to aid understanding, this textbook is suitable for undergraduates and graduates in physics and chemistry with a knowledge of atomic physics and who are familiar with the basics of quantum mechanics.

Professor Wolfgang Demtröder studied physics and mathematics, and received his PhD degree in 1961 from the University of Bonn. After working as an assistant professor and researcher at the University of Freiburg until 1967, he went as a visiting fellow to JILA in Boulder, Colorado. In 1970 he accepted a post as full professor at the newly founded University of Kaiserslautern, Germany, where he still works. Professor Demtröder was awarded the Max–Born–Award of the English and German Physical Society in 1995.
