The rate coefiiclent, k, , for the rcacuon 12 + F 2 '2 products has been measured at room temperature to be k, = (19 = 0.4) X 1O-15 cm3/moIecule s. The macroscopic rate IS compared to muxoscopnz cross-section data obtamed from molecular beam expenments and IS found to be consistent with the bunolecu

โฆ Synopsis
The inlrared emission of l*(*P1& aloms at 1315 pm has been observed m a fast-flow reactor from the renct~on of F atoms with iodine mokules. F atoms were produced either in an electronic discharge by dl-ation of a Iluorinakd compound or tn a mmbustor from rhc reaction of CA-F2 and Dz with helium dilucnt.. The lower bmit for Ihe microscopic branching ratio I'/1 was found to he 0.03 by comparison with the HF(Au -2) enusslon resuhing from the F+H, rcac~ton-
