Gas-phase rate coefficients and activation energies for the reaction of NO3 radicals with selected branched aliphatic aldehydes
Abstract
Using a fast-flow-discharge technique, absolute rate coefficients for the gas-phase reactions of the NO3 radical with a series of branched
k 1 = (1.0 ± 0.5) × 10−10exp[−(2598 ± 384)/T]/cm3 molecule−1 s−1,
k 2 = (2.7 ± 1.2) × 10−11exp[−(2063 ± 356)/T]/cm3 molecule−1 s−1,
k 3 = (5.5 ± 3.1) × 10−11exp[−(2296 ± 555)/T]/cm3 molecule−1 s−1,
k 4 = (3.7 ± 1.4) × 10−11exp[−(2184 ± 230)/T]/cm3 molecule−1 s−1.
