β relaxation of nonpolymeric liquids close to the glass transition

Abstract

The β relaxation of non polymeric pyridine-toluene solution is studied near glass transition. Both loss peak frequency and relaxation strength are affected by the glass transition. The relaxation is small Arrhenius temperature dependent. Observations were also made for some other viscous liquids. Results showed exhibited similar behavior for the other liquids, suggesting a generality in the phenomenon.
