Abstract
Rotational energy transfer in OH (X 2Πi, v=2) induced by collisions with He, has been studied using a two-laser technique. Strong propensities are found for conservation of total parity in collisions which change the rotational level and spin orbit component. These results have implications concerning the shape of the OH–He potential.Keywords
