Abstract

A supersonic molecular beam of scandium monosulfide (ScS), produced using a laser ablation/ reaction source, was interrogated by laser induced fluorescence. The fine and magnetic hyperfine interactions in the (0,0) B ²Σ⁺-X ²Σ⁺ band system (origin=12 940.402 cm^-1) were analyzed. The magnitude of the Stark effect was measured for the (^RR₂₄+^RQ₂₄)(0) and (^PP₁₃+^PQ₂₃) (1) branch features, giving dipole moments of μ(B ²Σ⁺)=5.60±0.04 D and μ(X ²Σ⁺)=5.64 ± 0.04 D. The spectroscopic parameters and dipole moments are used to develop a molecular orbital bonding model and are compared with the isovalent molecules ScO and ScNH.
