Abstract

Because of the lack of translational symmetry there is no interference and no coherence of the delocalized vibrations (phonons) in a glassy structure. Short- and medium-range order are of great importance in the classification of the vibrational mode in crystals. In silicate glasses, the IR and Raman spectra allow inferences about the degree of polymerization. In the fully polymerized network of aluminosilicate glasses, the high-frequency modes seem to be associated with tetrahedra, which themselves can differ in their composition and spatial arrangements.-R.A.H.
