Temperature Dependence of the Sound Velocity in a Polar Liquid: SO2
The adiabatic sound velocity and attenuation for liquid SO2 was measured in a temperature range between the solid and the gas phases (i.e. 200 to 260 K). The results are compared with recent inelastic neutron scattering data on similar temperature range. The extrapolation of these data to Q=0 coincide very well with the present hypersonic velocity from Brillouin experiments.
