Electronic structure of ScN: Jet-cooled laser-induced fluorescence spectroscopy

►1Σ+ symmetry for ground state of ScN molecule confirmed. ► Fundamental vibration in the ground state measured. ► Three new excited states with Ω = 1 observed. ► Fundamental vibrations and internuclear distances for new excited states measured. ► New excited states cannot be accounted for based on existing ab initio results.
