Absorption spectrum of NO3 and kinetics of the reactions of NO3 with NO2, Cl, and several stable atmospheric species at 298 K
The absorption spectrum of NO3 has been measured between 615 and 670 nm in the photolysis of Cl2-ClONO2-N2 and F2-HNO3-N2 mixtures. The absorption cross section was found to be (1.19 +/- 0.36) x 10 X cmS molecule at 622.3 nm, and this leads to a value of (1.85 +/- 0.56) x 10 X cmS molecule at 662 nm in good agreement with most recent studies. The rate coefficient for the reaction NO3 + NO2 N2O5 was measured to be (4.8 +/- 0.3) x 10 T and (5.8 +/- 0.8) x 10 T cmT molecule at total pressures of 24 and 40 torr of N2, respectively. A rate coefficient for the reaction between Cl and NO3 was derived from the NO3 behavior in the photolysis of Cl2 and ClONO2 mixtures and its value at 298 K is (2.7 +/- 1.0) x 10 cmT molecule s . In addition, upper limits were determined for the rates of reaction of NO3 with SO2, CO, CH4, H2O2, and CS2. 40 references, 7 figures, 6 tables.
