摘要

Laser induced fluorescence measurements of the rotational population distributions for the 16OH(X 2Πi, v=0, 1) products of the reaction of O(1D) with H2O and the 16OH(X 2Πi, v=0, 1) and 18OH(X 2Πi, v=0, 1) products of the reaction of O( 1D) with H2 18O are presented here. The rotational and vibrational distributions of the 16OH formed in the normal isotopic abundance reactions were found to be close to those expected if the energy of the reaction is statistically distributed amongst all available product states. Isotopic labeling of the oxygen atom in the reactant water molecule demonstrated that the vibrational distribution of the new 16OH bond formed is significantly more energetic than the remaining 18OH bond, while the rotational distributions were similar. These results are interpreted as H atom abstraction (or stripping) dynamics predominating over O atom insertion into the water OH bonds.
