|Title:||Mechanism of the Reaction, CH4 + O(1d2)-> CH3 + OH, Studied by Ultrafast and State-Resolved Photolysis/Probe Spectroscopy of the CH4 O3 van der Waals Complex|
|Published:||January 01, 2001|
|Abstract:||The mechanism of the reaction, CH4 + O(1d2) -> CH3 + OH, was investigated by ultrafast, time-resolved and high resolution, state-resolved experiments. Ultraviolet pulses photolyzed ozone in the CH4 O3 van der Waals complex, and the appearance rate and product state distribution were measured by laser-induced florescence. These data are best fit using a three-mechanism model. The three mechanisms were assigned to the dissociation of a methanol intermediate according to statistical theory, dissociation of a methanol intermediate before intermolecular energy redistribution, and an abstraction.|
