N2 - Depolarized light-scattering spectra have been measured for the molecular glass-former m-tricresylphosphate (m-TCP), for which the slow relaxation behaviour was known between Tgand 1·5 Tg. Considering scattering from TA sound waves and from local fluctuations, and using a viscoelastic model, a good description of the spectra is achieved, including the central (quasielastic) line. The quasielastic part is compared with the slow α-relaxation measured by NMR. The damping of the TA modes is much stronger than one expects from α-relaxation only. Connection is made with the fast relaxation seen in low-frequency Raman scattering.
