Real-time kinetic study of the reaction F+NO2

The title reaction was studied in real time by observing infrared fluorescence resulting from the competitive reaction F+H2. With N2 as a collision partner, the limiting rate constants were found to be k0=9.8±1.6×10−31 cm6 molecule−2 s−1 and k∞=3.2±0.8×10−11 cm3 molecule−1 s−1, as determined by fitting the experimental data to Kassel, and modified Lindemann–Hinshelwood models. Measurments with argon showed it to be slightly less effective as stabilizing the reaction complex. Calculations indicate that both FNO2 and FONO are formed in the reaction, with a product ratio of FONO/FNO2≊7.
