abstract = {Raman spectroscopy and extended X-ray absorption fine
structure (EXAFS) spectroscopy have been applied to find
evidence for isostructural substitution of chalcogen atoms
in pyramidal structural units of network glasses from
stoichiometric/pseudo-binary As2S3-As2Se3 system. The
obtained values of the nearest neighbours atomic distance
(rAs-Se = 2.37 ± 0.01 Å;
rAs-S = 2.33 ± 0.01 Å for As40Se30S30) suggest
the existence of mixed AsS2Se and AsSe2S pyramids in which
each of As atoms is bonded with S and/or Se atoms in
relation to S/Se ratio in composition, while Se atoms are
bonded only with As ones with the same bond distance in the
form of = As-Se-As = bridges that connect the main
pyramidal structural units. No evidence for existence of
heteroatomic or heteronuclear SeS bonding is found for the
examined glasses},
