✦ Synopsis

The local environment of antimony atoms in vitreous samples of the ternary system Sb 2 S 3 -As 2 S 3 -Tl 2 S is studied by 121 Sb Mo¨ssbauer spectroscopy. The results have been interpreted by means of EBV (empirical bond valence) and EBLV (empirical bond length valence) calculations. Variations in isomer shifts are attributed to changes in the environment of antimony atoms. The isomer shift is found to be a very sensitive parameter reflecting variations in the mean coordination number and in the mean Sb-S bond length. The results presented here
