Use of group theory in the interpretation of infrared and Raman spectra. [Tables, vibrational spectroscopy]

Application of the mathematical theory of groups to the symmetry of molecules is a powerful method which permits the prediction, classification, and qualitative description of many molecular properties. In the particular case of vibrational molecular spectroscopy, applications of group theory lead to simple methods for the prediction of the number of bands to be found in the infrared and Raman spectra, their shape and polarization, and the qualitative description of the normal modes with which they are associated. The tables necessary for the application of group theory to vibrational spectroscopy and instructions on how to use them for molecular gases, liquids, and solutions are presented. A brief introduction to the concepts, definitions, nomenclature, and formulae is also included.
