Abstract

A combined EPR/LMR spectrometer and fast-flow system has been used to investigate the reactions HO₂ + NO(k₁), HO₂ + OH(k₂), HO₂ + HO₂(k₃) at room temperature. The rate constants have been measured: k₁ = (7.0 ± 0.6) × 10^-12 cm³ s^-1 (P = 7-10 Torr);k₂ = (5.2 ± 1.2) × 10^-11 cm³ s^-1 (P = 8-10 Torr);k₃ = (1.65 ± 0.3) × 10^-12 cm³ s^-1 (P = 2.1-24.9 Torr). The conclusion is drawn from analysis of the literature and the present work that k₂ and k₃ do not depend on pressure up to 1 atm.
