STEREODYNAMICS OF THE REACTION 1(2))-2(UPSILON=0)-]OH(X-2-PI(I)UPSILON'=0,N',F)+H - STATE-RESOLVED LINEAR AND ROTATIONAL ANGULAR-MOMENTUM DISTRIBUTIONS(H)

The product-state-specific stereodynamics of the photon-initiated reac tion of O(D-1(2)) with H-2 has been investigated by polarized Doppler- resolved laser-induced fluorescence, under room-temperature bulb condi tions. Product-state-resolved differential cross sections, excitation functions, and rotational angular momentum alignments are reported for the channels leading to OH((2) Pi(3/2)(A'/A ''); v'=0,N'=5) and OH((2 ) Pi(1/2)(A'); v'=0,N'=14) at a mean collision energy of similar to 12 kJ mol(-1). The data are compared with (state-resolved) quasi-classic al trajectory (QCT) calculations of the linear and angular momentum di stributions and excitation functions conducted on the Schinke-Lester ( SL1) ab initio ground-state potential energy surface, under similar co nditions as the experiments. Overall, excellent agreement is obtained between the QCT calculated and experimentally determined stereodynamic al features. The results are discussed in light of other recent work o n this prototypical insertion reaction and on the related systems O(D- 1(2)) + HD and CH4.
