In the flowing afterglow system, strong emission spectrum of IF(B-X) has been observed from the reaction of F atoms with Iodine molecules. The IF(B) vibrational distribution was measured, it has a striking similarity to that of F atoms with other iodide flames, being Boltzmann for the lower vibrational levels (v' <5), but having an excess population for the higher levels. In addition, the IF(B) intensity shows a quadratic dependence on fluorine atom concentration. These results lead us to suggest that the simple three-body recombination of a ground state fluorine atom with an excited state iodine atom is the origin of the IF(B) in this reaction.
