Infrared and polarized Raman spectra of (NH4)JH(S04)1 have been recorded and analysed. Multiple bands are observed for the vibrational modes of SO:-and NH: groups. HSO; and SO:-ions are found to coexist with vibrational interaction between them. NH: ion is not rotating freely in the lattice.
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
