title: Vanadium speciation by XANES spectroscopy: a three-dimensional approach.
abstract: A library of X-ray absorption near-edge structure (XANES) spectroscopic data for V(V), V(IV) and V(III) complexes with a broad range of biologically relevant ligand has been used to demonstrate that three-dimensional plots of key XANES parameters (pre-edge and edge energies; pre-edge and white line intensities) can be used for the prediction of V oxidation states and coordination numbers in biological or environmental matrices. The reliability of the technique has been demonstrated by re-analysis of the published XANES data for a V(V)-dependent bromoperoxidase.
