Insertion and abstraction pathways in the reaction O(D-1(2))+H-2 -> OH+H

Rigorous quantum dynamical calculations have been performed on the ground 1 (1)A' and first ex cited 1(1)A " electronic states of the title reaction, e mploying the most accurate potential energy surfaces available. Product rov ibrational quantum start populations and rotational angular momentum alignm ent parameters are reported, and are compared with new experimental, and qu asiclassical trajectory calculated results. The quantum calculations agree quantitatively with experiment. and reveal unequivocally that the 1(1)A " e xcited state participates in the reaction.
