Molecular symmetry and spectroscopy -- 2d ed

Philip R. Bunker And Per Jensen. Issued By The National Research Council Of Canada. Includes Bibliographical References (p. 703-721) And Index. This book is intended for the high-resolution molecular spectroscopist who would like to learn how to understand molecules and molecular spectra using group theory. It explains the use of the molecular symmetry group and the three-dimensional rotation group in understanding molecules and their spectra. Examples are presented throughout which are felt to be the most useful for the high-resolution spectroscopist, including discussion of the hydrogen dimer and the ammonia dimer in detail. Topics covered include symmetry labelling of molecular energy levels, nuclear spin statistics, Hamiltonian operators, wave functions, energy levels and interactions, transition intensities and optical selection rules, non-rigid molecules, weakly bound cluster (or van der Waals) molecules, linear molecules, and electron spin double groups.
