Abstract

The radiative lifetimes of the HgBr(B) and HgI(B) states have been determined to be 23.7±1.5 and 27.3±2.0 ns, respectively, by fast photolysis of HgBr₂ and HgI₂ using e-beam-excited ArF and KrCl fluorescence. This experimental approach generated simple exponential decay curves which facilitated measurement of the lifetimes and the rate of quenching of the excited HgX (B) states by HgX₂ (X=Br or I) molecules. Although the lifetimes reported here are in agreement with previous experimental measurements, they contradict a recently published theoretical calculation.
