✦ Synopsis
The I*(* PI/z) + Brt 5z IBr + Br*(* Pr/z) reaction has been directly observed by monitoring both the decay of i* ftuorescence (1.3 p) and the appearance of Br* fluorescence (2.7 u) following laser photolysrs of i-CjF',I in flowing mLxtures with Brz and argon. The total rate for deactivation of I* by Brz, an upper limit on k*, is (1.95k 0.12) x IO6 S' to& , \here the uncertamty represents two standard deviations.
