CS+ (B2Σ+-X2Σ+) emission produced from Penning ionization of the CS(X1Σ+) radical

Article abstract of DOI:10.1063/1.440493

Emission spectrum resulting from the energy transfer reaction of He (2 ³S) with transient CS radical produced through a microwave discharge of Ar/CS2 mixture was observed in a flowing afterglow apparatus.A new CS⁺ (B²Σ⁺ -X²Σ⁺) band system due to He (2³S)/CS Penning ionization was identified in the 220 - 340 nm region.The dominant bands were the (v',O) and (O, v'') progressions, which was consistent with the prediction from calculated Morse potential Franck-Condon factors.Although the observed bandhead wavelengths of the major CS⁺ (B-X) emission werein good agreement with those predicted from the reported spectroscopic data, the (4,0) band was located at an abnormal position.It was interpreted as a consequence of vibrational perturbation in the B²Σ⁺ state.The relative intensities of CS⁺(B-X), CS⁺(B-A), CI, and SI emission were estimated to represent that the dominant pathway of the He (2³S)/CS reaction is Penning ionization.
