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)

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” 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
