OH(V,J) DISTRIBUTIONS FROM THE REACTION BETWEEN CH4 AND O((1)D(2)), INITIATED IN CH4-CENTER-DOT-O3 CLUSTERS

The nascent OH rovibrational distribution for the reaction CH4.O3+hnu2 66 nm-->CH3+OH+O2 are reported. The population ratio between the vibra tional levels was found to be v(0)/v(1)=1.0+/-0.2 (2sigma), v(1)/v(2)= 0.67+/-0.26, and v(2)/v(3)=1.5+/-0.2; and significant rotational excit ation was observed for all vibrational states. The asymmetric lambda d oublet is populated to a greater extent than expected statistically, b ut no measurable spin-orbit propensity was observed. Both the rotation al and vibrational distributions are somewhat cooler than those of the analogous 'free' reaction, CH4+O(1D2)-->CH3+OH.
