The recombination reaction O + O 2 → O 3 was studied by laser flash photolysis of pure O 2 in the pressure range 3–20 atm, and of N 2 OO 2 mixtures in the bath gases Ar, N 2 , (CO 2 , and SF 6 ) in the pressure range 3–200 atm. Fall‐off curves of the reaction have been derived. Low‐pressure rate coefficients were found to agree well with literature data. A high‐pressure rate coefficient of k ∞ = (2.8 ± 1.0) × 10 −12 cm 3 molecule −1 s −1 was obtained by extrapolation.
