Hello, Could there be any information or insight in the XANES data? Localized electrons might significantly change the edge structure for the system. Just a thought, Chris Dr. Christopher Patridge Assistant Professor of Chemistry Dept of Math and

Dear Maurits, My dissertation looked at the possibility that the kind of change you describe is accompanied by a discontinuity in the third cumulant parameter for (in this case) the nearest-neighbor bond. My evidence was not sufficiently convincing to allow for publication elsewhere, but it was

Dear XAFS specialists, We've performed an experiment at the ESRF in Grenoble to find experimental evidence of an electronic change in our system. We suspect, from ab initio calculations, that there is a change in how electrons are allocated in our Mn/Fe system. Calculations show that some elect
