Résumé

ABSTRACT Red and orange bands of laser-induced fluorescence in NiH have been recorded on a Fourier transform interferometer at Doppler resolution. The spectra show strong transitions to low-lying vibronic states which are not thermally populated in a laboratory source, and therefore do not appear in laser excitation spectra, but which would be expected to contribute significantly to any stellar spectrum. The strongest bands belong to the G [Ω′ 5/2]– X 2 2 Δ 3/2 , I [Ω′ 3/2]– X 2 , and 2 Δ 3/2 I [Ω′ 3/2]– W 1 2 Π 3/2 systems. Measurements are reported for 58 NiH, 60 NiH, and 62 NiH.
