Abstract

We have studied the 90 degree VV-polarized Brillouin scattering spectrum of the molecular glassformer salol and observed a previously unnoticed VV-dip feature at low frequencies for temperatures above 300K. This new feature is a consequence of rotation-translation coupling, as recently predicted by Pick, Franosch et al [Eur. Phys. J. B 31, 217, 229 (2003)], who showed its relationship to the Rytov dip that occurs in the corresponding VH spectrum. The analysis of the spectra shows good agreement with the theoretical predictions
