Polarised IR and Raman spectra of non-centrosymmetric Na3Li(SeO4)2·6H2O crystal-A new Raman laser material

Polarised IR and Raman spectra of Na3Li(SeO4)2·6H2O single crystal have been recorded. Discussion of the results has been based on the factor group approach for the trigonal R3c (C3v6) space group with Z = 2. The obtained results for the spontaneous Raman scattering have been used in the discussion of the stimulated Raman spectra of the material studied-a new Raman laser crystal.
