We study the electronic structure of NiO using resonant soft X-ray emission spectroscopy across the Ni L2,3 thresholds. We observe inelastic (Raman) features within 10eV of the elastic peak energy. At the L3 resonance, the features within 4eV are enhanced and can be directly assigned to the d-d multiplets of NiO, in correspondence to features observed in optical absorption spectra. Resonance enhancements of the triplet and singlet states resolved in energy confirm a spin-flip transition. Charge-transfer (CT) excitations are also clearly identified by resonance enhancement at photon energies corresponding to the satellites observed in the Ni L2,3 X-ray absorption spectra.
