We measured the O 1s and Ti 2p X‐Ray Absorption Spectroscopy (XAS) spectra of a series of ternary Ti oxides. The spectra of A1 2 TiO 5 are compared to those of TiO 2 and the physical mixture TiO 2 –Al 2 O 3 . The spectra reflect important differences in the electronic structure caused by changes in the chemical bonding. It is also shown that XAS can be used to distinguish a true compound like Al 2 TiO 5 from a stoichiometric mixture like TiO 2 –Al 2 O 3 . The differences in the spectra of NiTiO 3 , SrTiO 3 , BaTiO 3 and PbTiO 3 are discussed in terms of the different chemical environment and the local coordination. © 1997 by John Wiley & Sons, Ltd.
