摘要：

Polarized and depolarized Raman spectra of lithium, sodium and potassium digermanosilicate glasses of the composition 33 A2O 67[(1 - y)SiO2, y GeO2] and powder Raman spectra of crystalline Li2O · 2 GeO2 and K2O · 2 GeO2 are given. From the Raman spectra it is concluded that the structure of the glasses mainly consists of networks of SiO4 and GeO4 tetrahedra with one non-bridging oxygen atom, probably mixed in a random way. The structure is comparable to that of crystalline disilicates and digermanates. © 1979.
