Abstract
The coordination geometry of transition metal ions Cr3+, Mn2+ , Fe2+, Fe3+, Ni2+ and Cu2+ in acqueous solution has been studied by x-ray absorption near edge structure spectroscopy. The spectra have been analyzed in terms of succesive orders of multiple scattering contributions. The effect of the absorbing central atom, oxydation state, interatomic distance of the various metal ions and the particular site structure of Cu2+ are discussed.
