Several vitreous and crystalline compounds in the As2S3-Li2S system have been investigated by XPS. Analysis of the core S2p peaks led to the distinction of various types of sulphur atoms: bridging and non bridging: the binding energy of nonbridging sulphurs is similar to the one observed for Li2S which reveals their strong negative character.
