Abstract
Rate constants for the gas-phase reaction of NO3 radicals with 1-butene, 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 using NO3 LIF measurements. NO3 radicals were produced via thermal decomposition of N2O5 at ca. 400 K, i.e. N2O5+M → NO3+NO2+M.
Applying pseudo-first-order conditions, the rate constants for 1-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 (1.03±0.09)·10−11 and (5.49±0.42)·10−11, respectively (unit: cm3 molecule−1 s1).
