The rate constants for quenching of the B states of HgBr and HgI by the rare gases and simple halogenated molecules have been measured. The experimental approach consisted of photodissociating either HgBr2 or HgI 2 (in the presence of the desired quenching gas) and recording the subsequent radiative decay of the HgX (X=Br or I) excited-state population. The large rate constant determined for two-body destruction of HgBr (B) by Hg (1.3×10-10 cm3 sec-1) and bromine donors (Br2: 5.5×10-10 cm3 sec-1) enhances the attractiveness of HgBr lasers pumped by dissociative excitation of HgBr2.
