## 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

Rate constants for the reaction H02 + NO,(+ M) = HO\*N02(+ M) have been obtained from direct observations of the HOz radical using the technique of molecular modulation ultraviolet spectrometry. HOz was generated by periodic photolysis of Clz in the presence of excess Hz and 0 2 , and k l was determ
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
