It has been a long history of studing the vibrational spectra of inorganic glasses and a great deal of information has been accumulated by infrared absorption spectroscopy. With the emergence of laser as an intense monochromatic coherent excitation light source, laser Raman spectroscopy has become one of the effective methods to study vibrational spectra of glasses. Previously, the vibrational spectra investigation of glasses was concentrated on the theoretical calculation based on the tetrahedral model of simple oxide and analysis of vitreous structure by comparing the theoretical vibrational spectra with experimental ones. Such method has encountered lots of difficulties in case of rather complicated glass composition. Therefore, by means of X-ray diffraction analysis, vibrational spectra of crystalline and theory of the structural chemistry, some glass structure information can be obtained from vibrational spectra of glasses. The systematic investigation on vibrational spectra of binary silicate and binary borate glasses have been made. However, little work has been done for other glass systems or multicomponent glasses. In this paper, IE, and Raman spectra of multicomponent inorganic glasses have been investigated. Using IR and Raman spectroscopy, we studied the multicomponent glass systems, including silicate, borate, phosphate, germanate, tellurite and fluoroberyllate. Their vibrational spectra are reported, the possible bond vibrations corresponding to these peaks are also given. The relative Raman cross section of the main peaks of the glasses were calculated. Nonlinear susceptibility of the glasses were also calculated by the method suggested by Gan Fuxi. It can be found there appears some relation between relative Raman cross section and third-order susceptibility of glasses.
