The kinetics of the polarized luminescence of impurity molecules in the liquid crystal MBBA has been measured. The different components of the luminescence differ in kinetics because of an orientational relaxation of the molecules. The correlation functions characterizing the orientational relaxation of the distribution of excited molecules with respect to rotation axes along the director of the liquid crystal and perpendicular to it have been determined.
