✦ Synopsis

The reaction of CF, with NO, was studied at 296 2 2 K using two different absolute techniques Absolute rate constants of ( I 6 ? 0.3) X lo-" and ( 2 1-03+07) X lo-" cm3 molecule-' s-' were derived by IR fluorescence and UV absorption spectroscopy, respectively

The reaction proceeds via two reaction channels: CF, + NO, -CF,O + FNO. (70 t 12)% and CF, + NO, + CF,O + NO, (30 ? 12)%. An upper limit of 1 1 % for formation of other reaction products was determined. The overall rate constant was within the uncertainty independent of total pressure between 0.4 to 760 torr.
