Primary Radicals from the Radiolysis of Water

Critical Review of Rate Constants for Reactions of Hydrated Electrons, Hydrogen Atoms and Hydroxyl Radicals in Aqueous Solution

Kinetic data for the radicals H and OH, and the hydrated electron in aqueous solution have been critically reviewed. Rate constants of the radicals have been measured directly mainly by pulse radiolysis. When directly determined values have not been reported and steady-state determinations are available, selected and recommended values have been used to normalize relative rates. Data for over 3,500 reactions are tabulated.

Recent data have been compiled and evaluated and added, along with these data, to the NDRL/NIST Solution Kinetics Database.
