The rate of the reaction (1) NO + HOz + OH + NO2 was determined in an isothermal discharge flow reactor with a combined ESR-LMR detection under pseudo-first-order conditions in HOz. The rate constant was identical in experiments with two different HOn sources: F + H202 and H + 0 2 + M. The absolute

## Abstract The Absolute rate constants for the gasโphase reactions of NO~3~ with HO~2~ and OH have been determined using the discharge flow laser magnetic resonance method (DFโLMR). Since OH was found to be produced in the reaction of HO~2~ with NO~3~, C~2~F~3~Cl was used to scavenge it. The overa
The rate-coefficients for the reactions HO2 + NO = HO + NO\* (1) and HO\* + HO = Hz0 + 0, (2) have been remeasured by laser magnetic resonance using an improved experimental arrangement. Values of kl = (6-9 f 0.6) X lO-12 cm3 molecule-' s-l and k2 = (5.8 -c 09) X 10-l cm3 molecule-' s-' (one standar
Mixtures of N20, Hz, 0 2 , and trace amounts of NO and NO2 were photolyzed at 213.9 nm, at 245'-328'K, and at about 1 atm total pressure (mostly H2). HO2 radicals are produced from the photolysis and they react as follows: (la) Reaction (lb) is unimportant under all of our reaction conditions. Rea
