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 the 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 T0 was found. The latter is in good agreement with the value of T0 determined from the temperature dependence of the a-relaxation time. @S0163-1829~96!02126-1#
