Electronic De-excitation of O(1D) by Rare Gases—Vacuum-Ultraviolet Flash Photolysis of O2

Far-uv photolysis of O2 produces excited atoms O(1D) whose relative quenching constants with argon, krypton, and neon are kAr = 0.015, kKr = 0.09, kNe = 0.007 if kXe is taken as unity. These values are in good agreement with Cvetanović's relative efficiencies [J. Chem. Phys. 45, 8, 2888 (1966) ].
