Abstract

We report the first direct gas phase observations of the electronic transitions, 2Δ5/2, ν = 0 → 2Π3/2, ν = 0 and 2Δ5/2, ν = 0 → 2Δ3/2, ν = 1, in the NiH radical. From the observed transitions we obtained transition frequencies and electronic g factors. The observation of these electronic transitions by LMR has been possible only by employing the recently developed CO overtone laser. This work forms the first spectroscopic application of this new laser.
