John,
Since when theorists started to need real samples? I thought a simulation is equally enjoyable.

If the sample is not homogeneous, it doesn?t matter if you use EXAFS or XANES spectra, they originate from the same atoms.

Both initial and final products (EXAFS) of the synthesis were measured using the continuous flow approach whereas the intermediate products were recorded, in the glass capillary, using the stopped flow. In the attached figure, you can find the same (all products). At high energies of EXAFS, both initial and final measurements show smooth behavior whereas the oscillating pattern/bump was observed for the intermediate states.
