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, 20H+M yields H2O2+M, and 20H yields H2O+O 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)
