Abstract
Several new electronic transitions of NiF with red-degraded bandheads near 12896 and 13497 \wn were recorded and analyzed. All bands have a common lower level: namely, v=0 of the A $^{2}\Delta_{5/2}$ state. The observed $^{58}$NiF and $^{60}$NiF isotopologue splitting in each band suggests tentative assignments as the (3,0) and (2,0) vibrational bands of the [12.6]$\Omega$=5/2 - A $^{2}\Delta_{5/2}$ transition and the (2,0) band of a new [13.1]$\Omega$=5/2 - A $^{2}\Delta_{5/2}$ transition of NiF. Results of the analysis will be presented. The gas phase NiF molecules were produced using a nickel-lined hollow cathode in an argon-based electric discharge with a small amount of SF_{6}.
