Dipolar and quadrupolar freezing in (KBr)1-x(KCN)x

Abstract

Dipolar and quadrupolar susceptibility measurements are reported for the molecular glass system (KBr)1-x(KCN)x covering a wide range of frequencies. The results allow a direct comparison of the dipolar and quadrupolar anomalies and demonstrate unambiguously that the freezing in of the dipolar and quadrupolar degrees of freedom occurs at different temperatures. © 1986 The American Physical Society.
