Abstract:

The yields of hydrogen and oxygen from the flash photolysis of water vapour were measured over a range of flash energy, water vapour pressure, and pressure of added inert gas. Relative rates of the two reactions, 20HM yields H2O2M, and 20H yields H2OO were estimated. These data were combined with earlier results of Black and Porter and of Del Greco and Kaufman to evaluate absolute rate constants for reaction 1 for a variety of third bodies. The magnitude of these constants supports the earlier suggestion that the first reaction proceeds through a M-OH complex. Author
