✦ Synopsis
Absolute rate constants a t room temperature for the metathesis reaction C~FS + Br2 C2FSBr + Br and nd3F7 + Br2 CzFTBr + Br have been measured under V L P P conditions:
The radicals were generated through collisionless infrared-multiphoton decomposition of the corresponding iodides by irradiation from a high-power C02-TEA laser. The reaction of k 2 F ~ and &F7 with NO2 are briefly discussed in relation to the reaction of ks with NO2, which had been measured previously.
