Large mono glitch around k ~ 13.8 A-1 (E~3200 eV) on 4-3 perhaps? On 4/9/2018 11:04 AM, Miller, Elizabeth Christine wrote:
Hi all,
I am analyzing some sulfur K-edge EXAFS data taken at 4-3 at SSRL. When I use a k-weight of k^3 to plot, my oscillations at high k reach over 100, which doesn’t make sense to me. I have looked over the data with Riti, and it seems that while the XANES are rather self-absorbed due to high concentrations of sulfur-containing salt, the data can be normalized, and the EXAFS should contain some information. I’ve included screenshots in the attachment of plots of all of the k-weights as well as my parameters. The mixtures are solutions of organics (acetonitrile, 1,1,2,2-Tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether) with bis(trifluoromethane)sulfonimide lithium salt. I am also not hitting any other edges, as sulfur is the highest Z element in the solution. Any thoughts would be greatly appreciated!
Thank you,
Beth
