Abstract
Ultraviolet and x-ray excited photoelectron spectra and soft X-ray emission spectra have been measured for the compounds As2S3, Sb2S3, As2O3, Sb2O3 and Bi2O3. All compounds exhibit quite similar photoelectron spectra of the density of valence states which can be interpreted with the same model based on the atomic electronic properties of the compound constituents accounting for the chemical order and the chemical composition of the compounds. This model is confirmed by the X-ray emission spectra. Cluster calculations using the CNDO approximation have been performed for As2O3 and Sb2O3. The influence of the cluster symmetry, the cluster size and the CNDO parameters on the calculated spectra was investigated. Reasonable agreement between theory and experiment could be obtained using suitable chosen parameter sets.Keywords
