The coordination of uranium in solution –what can we learn from EXAFS spectroscopy?

EXAFS gives average values of all neighbor distances as a radial distribution function. The determination of the coordination number has a relative high error (10-25%), therefore the structure interpretation is strongly focused onto distance determination (delta R ± 0.01Å). EXAFS combined with Factor analysis allows separation of different species from solutions. EXAFS allows to korrelate structural features to thermodynamically proposed solution species.
