Notes:
The reaction of atomic hydrogen with O2(1Δg) has been investigated as a function of temperature, using a fast discharge-flow apparatus equipped for EPR detection of free radical species. The rate constant for the overall reaction was measured as (1.46 ± 0.49) × 10-11 exp(-4000 ± 200 cal/mol/RT) cm3/s. Evidence is presented which suggests that the reaction occurs principally via abstraction, H + O2(1Δg) → OH + O, rather than via physical quenching, H + O2(1Δg) → H + O2(X3Σg-).
