Abstract: 
The X- ray diffraction (XRD) and far infrared (IR) transmission spectra of sulfur enriched amorphous As-S-Ge alloys along the tie – line (GeS4)x (AsS3)1-x have been studied with respect to material composition. It is shown that XRD patterns exhibit broad halos, which are typical for the glassy state but the IR vibrational spectra exhibit two oscillatory modes at 310 cm-1 and 374 cm-1 that correspond to A - S bonds in pyramidal AsS3/2 structural units and to Ge-S bonds in tetrahedral GeS4/2 structural units respectively.
