Abstract
Polarized Raman spectra were measured in single crystals of lithium sulfate doped with different concentrations of lithium selenate. Weak features observed in the Ag scattering geometry on the low-frequency side of the sulfate ionν1 mode were identified as originating in theν1 andν3 intramolecular modes of the selenate ion. The site group splitting of the guest selenate ion in the host lithium sulfate crystal was the same as that observed in pure lithium selenate. The vibrational spectrum of a more concentrated fused salt sample was dominated by disorder effects.
