Abstract

State-to-state collision dynamics of molecular radicals were investigated by the laser-induced fluorescence technique in a pulsed, crossed-beam apparatus. Dramatically different product state distributions were observed for two prototypical radicals, NCO(X²$PI) and CH(X²$PI). Based on a quantum scattering formalism and general considerations of the potential energy surfaces these observations were interpreted as generic features for the inelastic scattering of ²$PI radicals. The differences observed for NCO and CH are the results of well-known Hund's coupling classification of linear molecules.
