Abstract:

The spin orbit relaxation of atoms has been investigated in a steady state infrared fluorescence experiment. A CW argon ion laser operating at 488 nm was used to photodissociate gas-phase Br into equal quantities of Bromine and Bromine atoms. The resulting 2.7 micron emission was observed as a function of added quenching gas. A steady-state analysis was used to determine quenching rates for SF6, N2, O2, He, Ne, Ar, Kr, and Xe, relative to quenching by the parent molecule. Limitations in the apparatus prevented determination of the quenching rate coefficient for Br2. Recommendations are made for improvements in the apparatus and analysis for future research.
