Abstract
Resonant fluorescent scattering of uv light absorbed by the 0,0 transition of the nitric oxide γ band at 226 nm was used to detect the decrease in NO concentration due to reaction with F2 in a standard flow tube geometry. Rate measurements were performed under pseudo-first-order conditions with F2 in excess at temperatures between 168 and 359 °K. These measurements yielded a temperature dependent bimolecular rate constant for the reaction of NO with F2 of 7.0×10−13 exp(−1150/T) with an estimated accuracy of ±30%.
