Abstract
Quasielastic light scattering (QLS) in propylene glycol is measured in a temperature interval 95-320 K in order to study the fast relaxation processes. A model of the fast relaxation is proposed that predicts t he growth of the QLS as a function of the free volume. By fitting the experimental data on QLS within the framework of the model, the Vogel- Fulcher-Tammann temperature T-0 was found. The latter is in good agree ment with the value of T-0 determined from the temperature dependence of the alpha-relaxation time.
