Collisional quenching processes of Cd(¹P₁) have been studied directly, using dye-laser excitation and time-resolved fluorescence. Absolute cross sections for the quenching of Cd(¹P₁) by several gases have been determined, and the branching ratios for production of Cd(³P_J) for the quenching molecules N₂, CH₄, C₃Hg, and i-C₄H₁₀ have been shown to be close to unity.
