Visible chemiluminescence in the spectral range 200-900nm has been measured for the reactions of F atoms with a range of inorganic iodides studied at reduced pressures (ca. 0.7 mbar). There is only one emitter present in all cases uiz. IF*(B). The IF*(B) vibrational state distributions and rotational temperatures are essentially the same for all the systems studied. The yield of IF* can be substantially increased by adding O$('A) to the flame or by increasing the F atom concentration. It is suggested that the origin of IF*(B) in these reactions and other similar systems previously studied may be the recombination reaction of spin-orbit excited iodine atoms with ground-state fluorine atoms.
