✦ Synopsis

The quenching of electronically excited chlorine atoms, CI( 3 'PI ?). by several gases has been studied using a small gain laser pulse method, based on photochemical Cl and I lasers, operating on spin-orbit transitions 2P,,Z,F+*P3,Z,F... The quenching efliciencies for HZ, D,, CO, and SF6 are shown to be high and it is suggested that quenching occurs via near-resonant electronic to vibration-rotation (E-V,R) energy transfer. Also the collisional broadening parameters of the 2P, ,?,,:, >-2P3,2,F. =z line of Cl for a number of atoms and molecules have been measured.
