Rayleigh–Brillouin scattering from acetic acid

Abstract
Rayleigh–Brillouin scattering is studied in acetic acid as a function of temperature over the normal liquid range. The Brillouin linewidth displays a maximum at 30°C. The spectra are analyzed in terms of the general viscoelastic theory of light scattering developed by Rytov. Relaxation times for reorientation and structural relaxation are derived from the data.
