A broadband 2.5‐ns‐long argon excimer photolytic source was used to initiate the reaction sequence resulting in the formation of Kr2F*. The resulting fluorescence signal at 400 nm depended on the radiative and quenching processes of Kr2* as well as Kr2F*. The radiative lifetime of Kr2F* was found to be 181±12 ns. The rate constants for quenching by F2 and Kr are 4.3±0.4×10−10 and 6.9±0.7×10−15 cm3 s−1, respectively. The Kr2* coupled lu, Ou lifetime is 280±30 ns and the rate constant for quenching of Kr2* by F2 is 2.1±0.2×10−10 cm3 s−1.
