The IR optical transmission spectra in the 4000–1000 cm-1 (2.5–10 μm) region in the chalcogenide glasses (ChG) of the ternary Ge–Sb–S system of stoichiometric Sb2S3–GeS2 and non-stoichiometric Sb2S3–Ge2S3 compositions are studied. The compositional dependences of the measured IR spectra connected with influence of O-, H- and C-based absorbed impurites are analyzed.
