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

Abstract

Far‐uv photolysis of O₂ produces excited atoms $\mathrm{O}{(}^1\mathrm{D)}$ whose relative quenching constants with argon, krypton, and neon are $$k_{\mathrm{Ar}}{\text{\hspace{0.17em}=\hspace{0.17em}0.015, k}}_{\mathrm{Kr}}{\text{\hspace{0.17em}=\hspace{0.17em}0.09, k}}_{\mathrm{Ne}}\text{\hspace{0.17em}=\hspace{0.17em}0.007}$$ if $k_{\mathrm{Xe}}$ is taken as unity. These values are in good agreement with Cvetanović's relative efficiencies [J. Chem. Phys. 45, 8, 2888 (1966) ].
