| Abstract: | Single crystal i.r. and Raman spectra are reported for CsNCS. The main spectral features are in accord with the factor group predictions. Many of the polarisation sensitive multiphonon modes can be accounted for by k = 0 frequencies but for others k ≠ 0 critical points are implicated. |
