Abstract
The pulse radiolysis method has been used to produce ground‐state hydrogen atoms in gaseous hydrogen and has been combined with fast Lyman‐α absorption spectrophotometry to observe these atoms directly with microsecond time resolution. The technique has been used to study the kinetics of the reaction H + O2 + M = HO2 + M, where M is H2. The rate constant for this reaction was found to have the value at 298°K. This value, together with earlier data for Ar as third body, gives at 298°K for the ratio of the efficiencies of H2 and Ar as third body in this reaction.
