In this paper the infrared spectra and Raman spectra of three series of glasses with multi-glassforming oxides havo been reported: I. SiO2, P2O5-SiO2, GeO2-SiO2 and P2O5-GeO2-SiO2. II. 15Na2O.15BaO.10RmOn.60SiO2.RmOn-B2O3, Al2O3, Ga2O3, SiO2, GeO2,TeO2, Nb2O5. III. 10%B2O3, GeO2, TeO2 gradually substituted SiO2 in 15Na2O.15BaO.70SiO2 glasses. The spectral peaks in Raman and IR spectra and vibration bonds of glass structure have been illustrated. The different structural states of GeO2 and TeO2 in alkali and alkali-earth oxides contained and non-alkali and alkali-earth contained glasses are analysed. It is pointed out that the structure of Al2O3 contained glasses is homogeneous! and the structure of B2O3 contained glasses is inhomogeneous.
