Upper limit for the rate coefficient for the reaction of OH with N2O5
Abstract
An upper limit for the rate coefficient for the reaction of
was measured to be 5.7×10−15 cm3
molecule−1 s−1 at 240 K. OH radicals were produced ia pulsed photolysis of a mixture of O3 and H2, ia the reaction of O(1D) with H2, in the presence of an excess of N2O5 with SF6
as the bath gas. The temporal profiles of OH, which followed pseudo-first order kinetics, were monitored by laser induced fluorescence. Concentrations of N2O5 were determined by UV/visible absorption. Using this limit for k1, the potential role of N2O5
