Abstract: | The rate constant for the CF3 + NO2 reaction (k2) was measured at room temperature in the range of total pressures 300–600 torr. The measurements were performed using the ruby-laser-induced pulsed photodissociation of CF3NO in the presence of NO and NO2 in combination with time-resolved detection of the absorption of He(SINGLE BOND)Ne laser radiation by CF3NO. The use of the CF3 + NO reaction as a reference gives k2 = (3.2 ± 0.7) × 10?11 cm3/s. Analysis of the end products of the CF3 + NO2 reaction shows that the contribution of the association reaction channel, which leads to the formation of CF3NO2, is rather significant (about 30% total yield). A reaction mechanism is suggested to account for the products observed. © 1997 John Wiley & Sons, Inc. Int J Chem Kinet 29: 203–208, 1997. |
