Abstract
Further investigations of the reaction O(1D)+NH3→OH+NH2 and the first results on the reaction O(1D)+ND3→OD+ND2 are reported. The OH and OD rotational distributions have been found to be statistical. Hotter than statistical vibrational distributions are measured. The spin state distribution is statistical, with a strong preference to populate the energetically lower Λ component in both spin states. A preliminary study of the NH2 product shows very little rotational excitation. An analysis of this radical’s vibrational hot bands was not carried out due to lack of detailed spectroscopic information. The total energy is found to be partitioned according to 〈fR(OH)〉?0.1, 〈fV(OH)〉?0.25, 〈fR(NH2)〉?0.04, and 〈fT〉?0.25.
