Hello! I don't have any X-Ray data to analyze in your app, I'm just seeking a visual display of each element's standardized/accepted X-Ray spectra (instead of a table of numbers). So far, I've downloaded the application, but I'm stuck on how to find this information. I would greatly appreciate it if you would be willing to provide the necessary steps to accessing this information or if you would be willing to direct me to the right source for that info. Thanks, Kyle
Kyle,
The F.W. Lytle Database from the Illinois Institute of Technology has a
number of standard spectra available for you to analyze.

Hello!
I don't have any X-Ray data to analyze in your app, I'm just seeking a visual display of each element's standardized/accepted X-Ray spectra (instead of a table of numbers). So far, I've downloaded the application, but I'm stuck on how to find this information.
"X-ray data" and "X-ray spectra" are somewhat ambiguous. In my experience, the generic "X-ray data" often implies X-ray fluorescence spectra, X-ray powder diffraction data, or an X-ray astronomy instrument (say, Chandra). We're mainly dealing with X-ray absorption spectroscopy (XAS) data here. But if you want "X-ray spectra" for each element, that may not really mean XAS, which will depend not only on the element but also on its atomic environment. Anyway, for XAS data, there are some example data included with the software we use, see https://github.com/xraypy/xraylarch/tree/master/examples/xafsdata, and https://github.com/bruceravel/demeter/tree/master/examples/data There are also online databases of experimental spectra at https://xaslib.xrayabsorption.org/, and https://mdr.nims.go.jp/ (FWIW, I would not recommend the data at the Lytle database - these data files are hard to turn into usable spectra, and the quality is spotty.) There are also calculations of predicted XAS spectra for some materials at https://next-gen.materialsproject.org/xas. To be clear, all of these spectra are represented by tables of numbers... which kind of leads me back to thinking you might not be asking about XAS data. Anyway, I hope that helps, --Matt
Is this what you had in mind? http://exafsmaterials.com/ReferenceSpectra.html Not all elements (nor all forms of a given element), but a good illustration. -R. On 2022-08-07 5:00 p.m., Kyle Draim wrote:
