Fully converged quantum cross sections for 4He-D2 (u= l,i=O) vibrational reliaxation were determined using the coupled-states method and a modikied version of the Gordon-Secrcst surface. First-order forbidden rotational transitions play a si@fkant role, comparable to that observed previously for the

A tunable dye laser was used to populate selectively a single rotational-vibrational state of N 2 ( B 'E , u' = 0, N' = O-l 5 ) . The population changes induced by collisions with He were determined using time-resolved spectroscopy in a flowing afterglow experiment. Total rotational transfer rates f
Individual state-?-to-state rotational transitions have been resolved in small angle scattering of po!arized CsF molecules on Ne, Ar, Cz Hg. Nz. CO, COz. CHFS at center of mass energies of about 0.1 eV. The absolute inelastic cross sections range from 5 A up to 600 A2 \_ Most cf our knowledge oi ine
