ResumoIR and Raman studies have been carried out on matrix isolated Cs2SO4, Cs2CrO4, Cs2MoO4, and Cs2WO4. The S, Cr, and Mo isotope shifts and the IR band intensity ratios of the E and B2 stretching modes have been used to evaluate the bond angles in these molecules. 18O substitution experiments have been carried out for Cs2WO4 in order to definitively establish the assignment of the ν(W–O) modes in this molecule.
