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

## Abstract Although three forms of lithium phosphate are known, a complete structural description of the highest temperature polymorph has not yet been given. In the present work, the phase transitions of lithium phosphate were investigated at high temperatures using Raman microscopy and xβray pow
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 <lΒ°C a1 =86\_5OC v&h rising temperature; the reverse change occurring at u78JDC with falling temperature. The observed changes in the spe
