Dear Cyril, I think you should read about normalization of XANES (NEXAFS) spectra at soft X-rays. It is a common problem of normalization with the short post-edge region. There are few tricks. I think you can find answer in already published articles (as an example) or on ifeffit mailing list (there are few already discussed topics) regards kicaj W dniu 13-02-08 08:28, Bajamundi Cyril pisze:
Hello,
I have here a very basic XANES data processing. I am but a novice in this XANES analysis.
In Bruce’s lecture “Athena: Data processing I mms://diamstream02.diamond.ac.uk/xafs-2011-2” posted in the Diamond Light Source website, he used the Fe_lepidocrocite.000 example to show how background removal and normalization is done. For the normalization range he used the range 150 – 742.610 because his original photon energy scan range is quite long [ Emin: -200 and Emax: 800].
However, say that your original scan range is only short e.g. within the range Emin : -30 to Emax: 80, such that you don’t see the non-wiggly range and you only see the a short portion of the post edge range, how does one set the normalization range for this data? Since I’m very new to XANES analysis, I keep second-guessing my choice of normalization range.
Your patience for answering this simple question will definitely help me in moving to the actual fingerprinting analysis that I need to do with my sample.
Many thanks.
Warm regards,
Cyril
