Laser-induced chemiluminescence study of the HgCl (BX) transition: Formation, radiation, and quenching processes

Abstract
The formation, radiation, and quenching of HgCl(B 2Σ+) have been investigated using a laser‐induced chemiluminescence technique. Hg/Cl2/Ar mixtures were irradiated at 253.7 nm by a frequency‐doubled nitrogen‐pumped dye laser. The Hg(6 3P1) reacted with Cl2 to yield HgCl(B 2Σ+). The time behavior of the HgCl(B 2Σ+) →HgCl(X 2Σ+) fluorescence was analyzed to obtain the following rate coefficients:
