The vibrational spectrum of Sb4O6 in the ps phase has been measured at
1000 K by high-temperature infrared spectroscopy. The four infrared-a
ctive absorption bands were observed at nu7 = 785.0 cm1, nu8 = 176.2 c
m-1, nu9 = 292.4 cm-1 and nu10 = 415.6 cm-1. By combining these result
s with data on the molecular geometry and the infrared-inactive modes,
as reported in the literature, the thermodynamic functions of Sb4O6 h
ave been calculated.
