Abstract:

Measurements of the rates of collisional quenching of HgCl and HgBr B 2 Sigma 12 by rare gases and halogenated molecules are reported in this paper. HgCl and HgBr fluorescence is produced by photolyzing HgCl2 and HgBr2 respectively using Xe2 radiation. A background pressure of Xe 100 torr ensures that the HgCl and HgBr is vibrationally relaxed. The rates are derived by using a modified Stern-Volmer analysis and estimated lifetime of the HgCl and HgBr B 2 Sigma 12 states of 29 nsec and 23 nsec, respectively. Author
