摘要：

The hypersonic velocity and sound attenuation for liquid CD3OD, CH3OH and CD3OD/6% D2O are reported for a temperature range of 190 K-300 K. The results, measured from Brillouin-Mandelstam scattering, indicate the presence of at least one viscous relaxation phenomenon, for which the relaxation time is evaluated. The non-Arrhenius behaviour of the latter magnitudes evidences the appearance at low temperatures of a second relaxational mechanism.
