While the spectrum of NiH has been extensively studied, only the Ω = 3/2 and 5/2 components of the strongly interacting ²Δ, ²Π and ²Σ⁺ molecular states arising from the 3d⁹ ground-state configuration of Ni⁺ have been reported for the deuterated form, NiD. We report on laser excitation and resolved fluorescence experiments that definitively locate rotational levels of v = 0–2 in the ²Σ⁺ state, and of v = 0 and v = 1 in the low-lying ²Π_1/2 state of ⁵⁸NiD.
