Abstract

A supersonic molecular beam of scandium imide, ScNH, and deuterated imide, ScND, were produced using a laser ablation/reaction source and interrogated by laser induced fluorescence and dispersed fluorescence spectroscopy. The field free fine and magnetic hyperfine interactions and Stark effect in the (0,0) Ã2Πr-X̃2Σ+ transition of ScNH (origin=15 023.033 cm-1) were analyzed. Ground state vibrational spacing for ScNH and ScND was measured. The determined permanent electric dipole moments are μ(Ã2Π)=4.08(7)D and μ(X̃2Σ+)=2.28(15)D. Plausible molecular orbital descriptions are given for the Ã2Πr and X̃2Σ+ states based upon the interpretation of the spectroscopic parameters and a comparison with other isovalent molecules is made.
