Stratospheric Reactions of Peroxynitric Acid.

Abstract

Both HO2 and NO2 play crucial roles in the chemistry of the upper atmosphere. For several years, these two species were thought to react via a radical disproportionation reaction, although it was suggested that a longer-lived complex could be formed according to reaction (1): HO2 + NO2 + M reversible reaction HOONO2 + M. The importance of reaction (1) has recently been verified by direct observation of HO2NO2 by Fourier transform infrared spectroscopy. Moreover, the rate of reaction (1) has been measured, and its reverse reaction (-1) has been studied. Also, RRKM theory has been applied to these data for reaction (-1) so that its rate can be reliably estimated as a function of both temperature and pressure. In another publication, the effect of HO2NO2 on tropospheric photochemical smog chemistry was discussed.
