Dear Scott, thank you for the interesting 'virtual' experiment. It will be very informative to see if linear combinations of two or more compounds can be unambiguously identified by EXAFS analysis. Environmental samples (soils, dirt, wastewaters, sediments, ..) are typical cases where such proble

Scott, Superb! I will be very eager to see the results of this sociology/statistics study. I'll probably participate and I strongly encourage others to do the same so that Scott can get some decent stats. B P.S. You can discourage the wiki from turning "Fe2O3" into a link by prepending an ex

Hi Wayne, All spectra were recorded on the same beamline on the same run (X-11B). Each has the same iron foil in the reference channel. The reference channel isn't great (the samples were on the thick side), but I'd judge the energy calibration drifted less than an eV over the course of the ru

Hi Scott, This sounds interesting. Can you tell me something about the energy calibration of the references and the samples? Are the reference compounds all correctly energy calibrated? I don't really care about the absolute calibration, just that the spectra are correct relative to each other.

Hi all, The EXAFS Divination Dataset is here: http://www.xafs.org/EXAFS_Divination_Set You may well be asking, "What is the EXAFS Divination Dataset"? It's a set of data collected on mixtures of iron compounds, mostly oxides of one sort or another. My research assistants have mixed random amou
