Jet-cooled laser-induced dispersed fluorescence spectroscopy of NiC: Observation of low-lying Ω = 0+ state

- A new low-lying Ω = 0+ state observed at Te = 5178 (6) cm−1.
- Based on ab initio calculations the state is plausibly assigned as a 0+ spin-orbit component of the first excited 3Π state.
- Harmonic and anharmonic wavenumbers for ground X1Σ+ and a3Π states determined.
- RKR potential energy curves constructed.
