A new A3Πi-X3Σ- electronic transition of NiO has been observed in the near infrared region extending from 2.1 to 2.6 μm. The molecule was excited in emission from an Ni hollow cathode discharge and the spectra were observed using a Fourier transform spectrometer. The observed spectrum consists of the 0-0 band for the 3Π0-3Σ1-, 3Π1-3Σ0- subbands and the 1-1 band of the 3Π1-3Σ0- subband. The subbands involving 3Π2 spin component were not observed. The molecular constants including the Λ-doubling constants in the excited A3Πi state have been determined. The principal constants for the new excited state obtained from this analysis are T0 = 4337.5554(12) cm-1, A0 = -283.3713(16) cm-1, and B0 = 0.494659(11) cm-1.
