Detailed kinetic studies of excited and/or transient species

Subsequent to the pulsed photolytic (193 nm) production of O(3P) in the presence of CF3I, rapid consecutive reactions lead to the production of IF(X1 sigma 3). All of our measurements are consistent with IF being produced via the reactions: O + CF3I yields OI + CF3 yields F2CO + F, and F + CF3I yields IF + CF3. This route can be quite efficient, and we estimate that > 10% of the O(3P) atoms can lead to IF molecules under suitable conditions.
