Double-channel excitation in the XAS spectra of divalent and trivalent iron complexes in water solution.

ABSTRACT

We present a detailed analysis of XAS spectra of divalent and trivalent iron complexes in water solutions. The interpretation of the spectra has been provided by multi-channel multiple scattering approach. On this basis, good agreement between experimental data and theoretical calculations has been obtained in both cases including two excitation channels in the final state.
