Hi Jan, Yes, it can be confusing to select the E0 value for spectra like this. The complication is that we basically use E0 for two purposes: for XANES and normalization, we use it as the energy where absorption starts. In this case, the first derivative at the Cu1+ position is perfectly rea

Sebastian, What is happening “in situ”? Are you heating the sample, flowing gas, or changing some other external conditions? The cleaner spectra are also those with larger oscillations, implying a more uniform local environment. That might suggest that the less clean spectra are from samples

Hi Chris, Using the single-scattering and multiple-scattering paths that have the same scattering atoms is not double counting. In general, including all the paths from a Feff calculation is what you ought to do to account for all of the EXAFS. But many paths will have weak contributions, and
