AbstractLaser-induced fluorescence has been used to investigate the reorientation of the molecular angular momentum due to inelastic collisions with atoms. We report on experiments for the Li2 (1IIu)-rare gas system, where the degree of polarisation of the emitted fluorescence has been measured. Within the framework of a classical theory mean angles for reorientation have been derived. Their dependence on the collision partner and the initial and final angular momentum is discussed.
