Effects of the phase transition between the high-temperature tetragonal phases of the CsScF 4 crystal were studied by Raman scattering. The appearance of new lines including a soft mode was observed below the phase transition point, in complete accordance with the new crystal symmetry. The behavior
The temperature dependence of the C=N Raman stretching mode of NHaSCN IS presented. Two bands at 2063 and 2072 cm-r give place to a smgle band at 2044 cm-' within <lยฐC a1 =86\_5OC v&h rising temperature; the reverse change occurring at u78JDC with falling temperature. The observed changes in the spe
