✦ Synopsis

The rate constant for the CF 3 ϩ NO 2 reaction (k 2 ) 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 CF 3 NO in the presence of NO and NO 2 in combination with time-resolved detection of the absorption of He 9 Ne laser radiation by CF 3 NO. The use of the CF 3 ϩ NO reaction as a reference gives k 2 ϭ (3.2 Ϯ 0.7) ϫ 10 Ϫ11 cm 3 /s. Analysis of the end products of the CF 3 ϩ NO 2 reaction shows that the contribution of the association reaction channel, which leads to the formation of CF 3 NO 2 , is rather significant (about 30% total yield). A reaction mechanism is suggested to account for the products observed.
