简介
We analyze the Ti2p X-ray photoemission spectroscopy (XPS) and photoabsorption spectroscopy (XAS) spectra in formally tetravalent Ti compounds such as TiO2, SrTiO3 and BaTiO3, by means of a TiO6 cluster model, paying particular attention to the interplay between the Ti3dO2p hybridization and the intra-atomic multiplet coupling. We also show that the satellite peaks observed in the Ti2p XPS and XAS spectra can be understood as charge transfer satellites, although they have until now been ascribed to the exciton satellite which originates from the excitation from the O2p to O3s states.
