The chain reaction of several organic bromides with olefins was induced by a KrF laser. In all cases we found a self-inhibition, leading to a termination of first order in the radical concentration. There is indirect evidence that it is due to molecular bromine, accumulated during the reaction in spite of the presence of olefins. It has not been noticed previously. We show that kinetic analysis is easy also for pulsed excitation, and the example CF3Br + C2H4 is studied in detail. We found rate constants for CF3 + C2H4 → CF3C2H4 (7.2·109 cm3 mol-1 s-1; this is in between two previous values) and for CF3C2H4 + CF3Br → CF3C2H4Br + CF3(1.2·109 cm3 mol-1 s-1) as well as preliminary values for some other reactions.
