|Title:||RAMAN-STUDY OF LICSSO4|
|Abstract:||Polarized Raman spectra of single crystals of LiCsSO4 are obtained. It is found that factor group analysis isolated fails to give a consistent interpretation of the spectra. Hence, a complementary calculation, based on a group theoretical method, is employed to obtain the relative intensities for all of the internal modes. This calculation yields zero intensity for the B1g mode of the nu-1-type of vibration, so that the corresponding observed band is/assumed to be the A(g) symmetry mode, exclusively. Several calculated intensities result in almost negligible values for other A(g) and B1g modes. This fact is particularly helpful in the analysis of experimental data thus improving assignments of the Raman bands.|
