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({tilde X}{sup 2}{product}) and CH(X{sup 2}{product}). 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 {sup 2}{product} radicals. The differences observed for NCO and CH are the results of well-known Hund`s coupling classification of linear molecules.
