We describe the use of an iterative Van Cittert deconvolution approach to isolate the LUI-edge from the LII-edge EXAFS and MEXAFS signals for the 3d transition metals. The deconvoluted LIII-edge EXAFS data is in agreement with theoretically generated LIII-edge data, thus demonstrating the validity of this approach. Results from the deconvolution of the MEXAFS data also qualitatively agree with previously published MEXAFS data on the same elements at the K-edge.
