| dc.description | The L<sub>2,3</sub> edges of compounds containing tetrahedrally coordinated, isoelectronic d<sup>0</sup> transition-metal oxyanions, TiO<sub>4</sub><sup>4-</sup>, VO<sub>4</sub><sup>3-</sup>, CrO<sub>4</sub><sup>2-</sup> and MnO<sub>4</sub><sup>-</sup> have been measured using electron energy-loss spectroscopy (EELS). The general shape of the electron energy-loss near-edge fine structure (ELNES) is found to be remarkably similar for these oxyanions and arises from the atomic multiplet spectrum of the d<sup>0</sup> transition-metal ion modified by the tetrahedral field due to the oxygen ligands. The observed structure is also discussed within the framework of molecular-orbital (MO) theory. The possibilities of using these spectra as fingerprints for d<sup>0</sup> transition-metal ions in tetrahedral coordination is discussed. The structure observed at the O K edges is also commented upon in the light of these findings. |
