✦ Synopsis

The emission spectrum of the NiF radical has been recorded by high-resolution Fourier transform spectroscopy in the region 6000-12 000 cm -1 . Numerous new near-infrared bands were observed. In this paper three electronic transitions are analyzed leading to the identification of two new electronic states: a [12.0] 2 7/2 state and a [11.1] 2 3/2 state located, respectively, at 12 008.89 and 11 096.05 cm -1 above the X 2 3/2 ground state. These electronic states can be correlated to the [3d 8 ( 3 F)4s] 2 F atomic term of Ni + as predicted by Carette et al.
