Abstract
Rate constants for the gas-phase reaction of NO3 radicals with I-buten e, trans-butene, 2-methyl-2-butene and 2,3-dimethyl-2-butene have been obtained in a flow system at 298+/-2 K and a pressure of 3 mbar He us ing NO3 LIF measurements. NO3 radicals were produced via thermal decom position of N2O5 at ca. 400 K, i.e. N2O5+M --> NO3+NO2+M. Applying pse udo-first-order conditions, the rate constants for I-butene and trans- butene were found to be (1.04+/-0.11). 10(-14) and (3.74+/-0.45). 10(- 13), respectively. For 2-methyl-2-butene and 2,3-dimethyl-2-butene the rate constants were obtained under second-order conditions to be (1.0 3+/-0.09). 10(-11) and (5.49+/-0.47). 10(-11), respectively (unit: cm( 3) molecule(-1) s(-1)).
