Abstract

Using a model based on the theory for hierarchically constrained relaxation of Palmer et al., it has been possible to account for the quadrupolar freezing of the CN ion in KBr-KCN alloys observed in both Brillouin scattering and low-frequency shear resonance. In particular, the small change in the glass-transition temperature with probe frequency can be accounted for.
