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.
