Paper Abstract

Collisional depolarization of fluorescence is experimentally studied for 1,4-bis[2-(5-tolyloxazolyl)benzene] in He, Ar, and Xe solvents under the pressures ranging from zero to atmospheric. The results are interpreted within the Keilson- Storer model of the orientational relaxation and rigid body collision dynamics. The rate of the fluorescence depolarization vs. the buffer gas concentration is demonstrated to be very collision specific, thereby allowing one to extract information about the strength of the angular momentum scrambling in a binary collision.
