✦ Synopsis

The laser-induced fluorescence excitation spectrum of jet-cooled NiF has been studied in the range 435-570 nm. Eight electronic transitions, involving four high-lying components and two lower states, the ground state X 2 3/2 , and the low-lying state [0.25] 2 , respectively, have been recorded. Two new components are identified for the first time and their rotational constants are determined. The [20.4] 3/2 component is assigned as the v = 1 level of the previously known [19.7] 2 3/2 state. The [20.3] 3/2 component may be linked to the component of an unreported quartet state. The previously reported [20.0] 2 1/2 component is reassigned as a subcomponent of 2 .
