Polarization-dependent Ti K X-ray absorption and emission studies of Ti2O3 single crystal

► Remarkable polarization dependence of Ti K XAS and XES spectra for Ti2O3. ► High anisotropy of unoccupied Ti 4p bands reflects MIT of Ti2O3. ► Similar feature between Ti Kα Raman and XAS spectra. ► 2p4p monopole transition is observed as a broad structure in Ti Kα Raman spectra.
