The branching ratio, R, for N2 O2 and NO production in the O1DN2O reaction at 290 K has been measured to be 0.73 or - 0.11 and 0.92 or - 0.10 for hot and thermal O1D, respectively. O1D was produced from N2O photolysis at 184.9 nm. The product N2 was determined by gas chromatography NO and its oxidation product NO2 were each determined with a chemiluminescence analyzer. Arguments are given that the O1DN2O reaction in the stratosphere is dominated by thermal O1D and a value of R 0.9 or - 0.1 is recommended for stratospheric modeling. An unsuccessful attempt at measuring HNO2O3 kinetics is described. Author
