Laboratory Measurements of NiH by Intracavity Laser Absorption Spectroscopy

Abstract
The visible electronic spectrum of the NiH B 2Δ5/2-X 2Δ5/2 transition has been recorded with rotational resolution by intracavity laser absorption spectroscopy. The gas-phase NiH molecules were produced in an electric discharge using a nickel cathode in a pure hydrogen atmosphere at 1-3 torr total pressure. Peak positions for the NiH isotopomers are presented. 58NiH and 60NiH have been observed in sunspots, and attempts to observe NiH in stellar spectra are underway.
