摘要：

The primary features of the Raman and infrared spectra of AX2 tetrahedral glasses are associated with the edges of the vibrational bands calculated by Sen and Thorpe. The dominant Raman peak is assigned to a singular matrix element rather than a peak in the density of vibrational states. Simple expressions are developed which yield useful values of the vibrational force constants and intertetrahedral angles for vitreous SiO2, GeO2, and BeF2. © 1979 The American Physical Society.
