Abstract

The rate constant for the gas-phase reaction of isopropyl peroxy radicals with NO has been measured over the temperature range of 201-401 K using chemical ionization mass spectrometric detection of the peroxy radical. The temperature dependent expression for the rate constant was found to be k(T) = (2.7 ± 0.5) × 10-12 exp{(360 ± 60)/T} cm3 molecule-1 s-1 which gives a rate constant of k = (9.0 ± 1.5) × 10-12 cm3 molecule-1 s-1 at 298 K. This value is a factor 1.8-2.6 higher than previous measurements.
