Abstract

We present and discuss the Ti 2p and O 1s X-ray absorption spectra (XAS) and resonant photoelectron emission spectra (RPES) of the various polymorphic forms (TiO2-II, rutile and anatase) of TiO2. The largest differences between the Ti 2p XAS of polymorphs of TiO2 are observed inthe region of the double peak structure of the L-3 edge. A strong delocalization of the excited 3d electron in this region is concluded from the RPES at the L-3 threshold of Ti. The differences in XAS are attributed to increasing strength of the crystal field caused by delocalization of the excited 3d electron. (C) 1997 Elsevier Science Ltd.
