Abstract

The results of comparison of spectral position of the LF bands of As-S glass sys­tem with theoretical calculation of vibrational spectra of different clusters (As2S3,

As2S5, As4S6, As6S9) in the LF region (5-100 cm' ) are given. Calculated distribution of clusters lengths f(L) for As2S3 glass
