Theoretical investigation is made for the polarization dependence of resonant X-ray emission spectroscopy (RXES) of TiO[sub 2]. In Ti 2p→3d→2p RXES, a dramatic resonant enhancement of a 13 eV inelastic peak is predicted with TiO[sub 6] cluster model, when the incident photon energy is tuned to a satellite of the Ti 2p XAS. A strong polarization dependence of this RXES is shown in the calculation, and confirmed by recent experimental observations. These results suggest strongly that the satellite of the Ti 2p XAS originates from the excitation to the anti-bonding state between the Ti 3d and O 2p states due to the covalency hybridization, i.e., it is the charge transfer satellite. © 2000 American Institute of Physics.
