Laboratory Measurements of NiH by Intracavity Laser Absorption Spectroscopy

The visible electronic spectrum of the NiH B super(2) Delta sub(5/2)-X super(2) Delta sub(5/2) 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 hyd...

Zusammenfassung:The visible electronic spectrum of the NiH B super(2) Delta sub(5/2)-X super(2) Delta sub(5/2) 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. super(58)NiH and super(60)NiH have been observed in sunspots, and attempts to observe NiH in stellar spectra are underway.
