Electronic structure of MnS studied by resonant inelastic soft X-ray scattering

The electronic structure of MnS was studied using resonant inelastic soft X-ray scattering (RIXS) from 2p 6 3d 5 →2p 5 3d 6 →2p 6 3d 5 channel. The d-d excitation and charge-transfer (CT) excitation were obtained which were resonant at excitation energies corresponding to L absorption edge and the satellites, respectively. RIXS and XAS spectra were simulated by Hartree-Fock method under atomic SO 3 and cubic O h symmetries. The crystal field 10 Dq value was evaluated to 0.80eV—0.85eV. The stronger CT excitation of MnS than that of MnO originates from its narrower bandwidth.
