Abstract
Brillouin scattering is used to study concentration and temperature dependence of transverse acoustic phonon frequency ω TA (110) in (KCN) x(KBr) 1−x mixed crystals. Unlike pure KCN, mixed xrystals with x < 0.75 show no phase transition upon cooling, however, in these crystals we find a minimum in ω TA as a function of temperature. This minimum can be understood in terms of dynamical theory of rotation-translation coupling in molecular crystals.
