J. Eberhard et al., REACTION OF ISOPROPYL PEROXY-RADICALS WITH NO OVER THE TEMPERATURE-RANGE 201-401 K, Journal of physical chemistry, 100(3), 1996, pp. 993-997
The rate constant for the gas-phase reaction of isopropyl peroxy radic
als with NO has been measured over the temperature range of 201-401 K
using chemical ionization mass spectrometric detection of the peroxy r
adical. The temperature dependent expression for the rate constant was
found to be k(T) (2.7 +/- 0.5) x 10(-12) exp{(360 +/- 60)/T} cm(3) mo
lecule(-1) s(-1) which gives a rate constant of k = (9.0 +/- 1.5) x 10
(-12) cm(3) molecule(-1) s(-1) at 298 K. This value is a factor 1.8-2.
6 higher than previous measurements.
