Dear Matthew, 

Sure, the raw data and/or spectrum can be added to the database.  For this sample, the 1st derivative of the Fe foil was 7.112 keV.  I can also provide individual scans for the database, if needed.  Is there any interest in the As K-edge of this sample, too?  I have that one as well.

Thanks!  May I add it to the ALS 10.3.2 reference collection?

What is the standard of energy calibration?  Is the Fe metal edge at 7110.75eV, 7112eV or what?

Dear Shaofeng,

I am attaching the averaged, raw data and Fe K-edge EXAFS spectrum (extracted using SixPack) of scorodite.  The mineral was prepared following the procedure outlined in Paktunc et al. (2008).  The data were collected at the Stanford Synchrotron Radiation Lightsource in transmission mode with the sample housed in a liquid nitrogen cryostat.  You can find additional details on the preparation of the sample and data collection from the publication where the spectrum is reported and modeled (van Genuchten et al. 2014, Geochimica et Cosmochimica Acta).

Please let me know if you have any other questions about data collection.

Best,

    Dear all,
    Can anyone have Fe K edge exafs spectrum of scorodite share a copy?
    Thanks in advance.
