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 (1.7 ± 0.4) × 1010M−2·sec−1 at 298°K. This value, together with earlier data for Ar as third body, gives kH2 / kAr = 2.0 at 298°K for the ratio of the efficiencies of H2 and Ar as third body in this reaction.
