Large (centimetre size) single crystals of lithium hydroxide monohydrate, LiOHβ’H 2 O, were grown by slow evaporation of an aqueous solution at ambient temperature. Infrared reflectivity and Raman spectra of the single crystals were observed for the first time and studied experimentally at room tempe

## Abstract The bismuth triborate (BiB~3~O~6~; BIBO) single crystal has been studied by Brillouin and Raman spectroscopy. Using Brillouin spectroscopy the propagation of the acoustic phonons in [100], [010], [001], [110] and [011] directions has been analyzed. The influence of birefringent and opti
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.
