Abstract: The $X^{2}\Pi_{3/2}$, $A^{2}\Delta_{5/2} (161 cm^{-1})$ and $B^{2}\Sigma^{+} (1,768 cm^{-1})$ low-lying states of NiCl have been recently identified. Transitions linking these states to upper $[21.9]^{2}\Delta_{5/2}$, $[24.5]^{2}\Pi_{3/2}$ and $[24.9]^{2}\Pi_{1/2}$ states have been rotationally analyzed. Laser induced fluorescence experiments allowed the identification of the $X ^{2}\Pi_{1/2} (382 cm^{-1})$ and $A ^{2}\Delta_{3/2} (1,646 cm^{-1})$ spin-orbit components. All the low-lying states of NiCl associated with the nickel 3d atomic orbital are now observed. In addition we identified a new electronic state located at $21,608 cm^{-1}$. This state is linked to all the five spin-orbit components of the X, A and B states. High resolution Fourier transform experiments made possible the analysis of three of these transitions. Laser induced dispersed fluorescence suggest that this state is also linked to a new low-lying state $(1,378 cm^{-1})$ which could be a component of a quartet state of NiCl.
