Abstract
Multiple scattering from the outer shells of an imidazole ring contribute strongty in the EXAFS data over an extended k-range and it is essential to incorporate this for an accurate structure determination. We show that the multiple scattering formalism is able to produce the correct distances for all the atoms of an imidazole ring coordinated to cooper.
