Multiple-scattering calculations on a series of M(H2O)62+ complexes with M V to Cu

Abstract The metal K-edge X-ray absorption spectra of a series of M (H 2 O) 6 2+ complexes with M  V to Cu have been recorded in aqueous solution. After the white line, all spectra are characterized by a structure whose intensity depends on the absorbing metal. From multiple-scattering (MS) calculations, it has been shown that this structure is due to the collinear MS paths M → O → M → O → M. The influence of the metal is understood by the analysis of the p phase shifts of the scatterers.
