Re: Plotting chi(R) from FEFF in XAS Viewer (Larch) with phase correction (Matt Newville) ---------------------------------------------------------------------- Message: 1 Date: Tue, 13 Dec 2022 16:53:03 -0600 From: Matt Newville <newvi...@cars.uchicago.edu> To: XAFS Analysis using Ifeffit <ifeffit@millenia.cars.aps.anl.gov> Subject: Re: [Ifeffit] Plotting chi(R) from FEFF in XAS Viewer (Larch) with phase correction Message-ID: <ca+7esbr+dct8hfwntm2t+tonyhqw4iqwfbbbjoecn4ese+i...@mail.gmail.com> Content-Type: text/plain; charset="utf-8" Hi Liam, Yes, this is not currently available. It would not be hard to enable, but I am not sure it is a great thing to do. I admit that I sort of find that phase-correction plots need a lot of explanation, and so are prone to causing confusion. They might be useful for Pt metal, but they cannot really be correct for multi-atomic systems. Well, I guess "correct" is not the only consideration ;). I guess I would ask if there are suggestions and input from people teaching XAFS on whether phase corrections (and probably a handful of other "tricks" or analysis variations) are actually useful or just confusing.
