Faraday communications. A pulsed crossed supersonic molecular beam study of the reaction C(3P)+ OCS(X1Σ+)→ CS(a 3Πr, X1Σ+)+ CO(X1Σ+)

Abstract

The C + OCS → CS + CO reaction has been investigated in a pulsed crossed supersonic molecular beam experiment at a centre-of-mass kinetic energy of 0.32 eV. CS radicals, produced in both the a ³Π_r and X ¹Σ⁺ states, have been detected by laser-induced fluorescence (LIF). A newly observed CS transition, A ¹Π–a ³Π_r, is also reported. Comparison of relative LIF intensities following CS(a ³Π_r) and CS(X ¹Σ⁺) excitation, shows that the reaction pathway producing CS(a ³Π_r)+ CO(X ¹Σ⁺) is highly efficient.
