Talk:Extended X-ray absorption fine structure

A few-sentence discussion of the theory of EXAFS and a figure illustrating what the data looks like would do wonders for this article. Alison Chaiken 04:25, 17 February 2006 (UTC)

The link to the trivalent lanthanides study does not seem to work. Is it temporary?--Misty Ping (talk) 22:03, 24 June 2009 (UTC)

This paragraph is verbatim from http://srs.dl.ac.uk/xrs/Theory/theory2.html: X-ray absorption spectra are produced over the range of 200 – 35,000 eV. The dominant physical process is one where the absorbed photon ejects a core photoelectron from the absorbing atom, leaving behind a core hole. The atom with the core hole is now excited. The ejected photoelectron’s energy will be equal to that of the absorbed photon minus the binding energy of the initial core state. The ejected photoelectron interacts with electrons in the surrounding non-excited atoms. —Preceding unsigned comment added by 128.62.35.173 (talk) 07:18, 22 October 2009 (UTC)

I changed "number of xrays" in the introduction to "number of xray photons" as this makes more sense. 85.127.140.118 (talk) 12:10, 5 December 2010 (UTC)

Importance
I will admit to some bias, as EXAFS is my specialty, but does it really rate as only "low" importance in the Spectroscopy project? Low importance is defined as "subject is peripheral knowledge, possible trivial," with the tip that "most likely you will not recognize the subject."

I would be fairly shocked if a printed encyclopedia of spectroscopy did not include an entry on EXAFS.

I propose it be changed to "mid" importance for Spectroscopy. This would place it on par with Auger electron spectroscopy, NEXAFS, surfaced enhanced Raman spectroscopy, and XANES.SarahLawrence Scott (talk) 20:39, 19 February 2012 (UTC)
 * Seconded. EXAFS is equally as relevant as NEXAFS/XANES and XRF.Memcbr (talk) 06:48, 19 June 2016 (UTC)
