Raman scattering is used to make a dynamical study of the disubstituted and perdeuterated diacetylene pTS-D in monomer crystal from, where an incommensurate phase exists from T, = 155 K to r; = 195 K. The low-frequency polarised Raman spectra in the temperature interval 9-300 K show that the phase t
