✦ Synopsis
We have studied the 193 nm photodissociation of N20-H20 complexes produced in a supersonic jet resulting in the reactantpair reaction, N20*HZO+hv+20H+N,.
Measured internal energy, spin-orbit and n-doublet distributions in OH by laserinduced fluorescence suggest a reaction scheme much different from the corresponding bimolecular reaction, 0( 'D) + H,O+20H, observed in bulb experiments. The reaction should proceed slowly through the 0 ( 'D) +O( 3P2) curve crossing and a relatively long-lived reaction intermediate.
