Branching ratios for electronically excited oxygen atoms formed in the reaction of N+ with O2 at 300 K

Article abstract of DOI:10.1063/1.450377

Absolute branching ratios for production of O (³P) , O(¹D), and O(¹S) irrthe reaction of N+ with O2 are measured using the flowing afterglow/visible chemiluminescence technique.The O(¹S) product is monitored by the O(¹S)-O(¹D) emission at 557.7 nm.The O(¹D) product is monitored via sensitized fluorescence at 760 nm from O2(b¹Σ_g⁺) formed by energy transfer from O(¹D) to O2(X³Σ_g^-).Absolute O(¹D) and O(¹S) yieldsof70+/-30percent and <*>0.1percent, respectively, of the total atomic oxygen product are inferred by comparison to the known O(¹S) and O2(¹Σ_g⁺) emission intensities from the reaction of Ar(3P) with O2.The low O(¹S) yield is also obtained directly from the relative O(¹S) and O2(¹Σ_g⁺) emission intensities from the title reaction.A qualitative reaction mechanism consistent with these observations is presented.
