Fine-structure transitions of alkali atoms induced by collisions with diatomic molecules are shown to be strongly influenced by a dynamical feature that is completely absent when the collision partner is a rare gas. The effect is a nonadiabatic coupling caused by the anisotropy of the molecule. Calculations for Rb(5/sup 2/P/sub 1/2/)+H/sub 2/ and for Rb(5/sup 2/P/sub 1/2/)+He are in good agreement with recent experiments and explain the dramatic difference between these two systems.
