✦ Synopsis

X-ray absorption K-edges, fluorescent K-bands, and primary emission L2.3-bands of sulphur in crystalline and amorphous phases of semiconductor compounds AsSI, AgAsS2, GeAsS, GeS2, and As/S 3 have been investigated. The superposition of X-ray spectra of different kinds using the common energy scale reveals the electron structure of the compounds investigated and the character of chemical bonding in them. For AsSI, AgAsS/, GeAsS and As2S3 it is found that by transition from crystal to glass the electron density of states distribution in the valence and conduction bands does not change because of the too little changes of the short-range ordering by amorphization.
