Measurements on O(1D)/N2O and HNO2/O3 Kinetics.

Abstract

The branching ratio, R, for N2 + O2 and NO production in the O(1D)/N2O reaction at 290 K has been measured to be 0.73 + or - 0.11 and 0.92 + or - 0.10 for hot and thermal O(1D), respectively. O(1D) 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 O(1D)/N2O reaction in the stratosphere is dominated by thermal O(1D) and a value of R = 0.9 + or - 0.1 is recommended for stratospheric modeling. An unsuccessful attempt at measuring HNO2/O3 kinetics is described. (Author)
