We report an investigation of the long wavelength phonons of TlSbS2 performed by far-infrared Fourier transform spectroscopy. In close agreement with our previous Raman work, we find strongly polarized data. Significant differences appear between the two set of infra-red and Raman frequencies which correlate well with the centrosymmetric character of some of the linear units which couple to constitute the layer. © 1987.
