Abstract
In this paper we present a direct evidence o f the influence of hydrogen atoms on the XANES spectra of transition
metal complexes in aqueous solution. The metal K-edges of Ni2+ and Co2+ are analyzed by multiple scattering theory using
different clusters around the absorber and different final state potentials. On this basis the presence of hydrogen atoms has been
found to be necessary to reproduce the width and the relative amplitude ratio of the experimental features.
