Abstract
Polarization dependence of soft-x-ray Raman scattering was investigated at the Ti 2p absorption edge of TiO2. Strong Raman scattering feature appears about 14 eV below elastic peaks with strong polarization dependence. These Raman scattering structures are charge transfer excitations to the antibonding state between 3d1L-1 and 3d0 states, because they are enhanced when the incident photon energies are tuned at satellite structures of Ti 2p absorption spectrum. Broad Raman scattering structures are found between 3 eV and 10 eV below elastic peaks. They are assigned to be nonbonding type charge transfer excitations or interband transition from O 2p valence to Ti 3d conduction bands, which includes the crystal field splitting in D2h symmetry with two Ti-O bond lengths.
