The single crystal Raman spectra of orthorhombic K,SeO,, Rb,SeO, and Cs2Se0, are reported. Whilst the internal modes experimentally observed are in accord with the factor group prediction, fewer external modes than the predicted are observed.
The room temperature polarized Raman spectra of single crystal Li,SeO, are assigned using a factor group analysis. The internal optic modes of the selenate ion are responsible for Raman bands from 920 to 440 cn-I, the translational optic modes of the lithium occur in the interval from 444 to 290 cm
