Abstract
The specific features of hypersound propagation in aqueous solutions of nonelectrolytes in dependence of frequency and temperature have been investigated using Brillouin spectroscopy. Nontrivial temperature behavior of hypersound at small Brillouin scattering angles is observed in the vicinity of solution singularity. The temperature dependences of hypersonic velocity in aqueous solutions of methylpyridines and acetone at different frequencies have been analyzed.
