Hello, yet another one... sorry today is my day... With Athena it appears that I can simply (maybe too simply) click on a button and plot the phase shifted spectrum in R-space. How can I try to do the same using IFEFFIT from the command line? In practice, using IFEFFIT we can plot the fitted spectrum and the FT'ed experimental spectrum, but the plot does not consider the phase shift. We need to extract the phase shift in oder to translate the plot to show the phase shifted spectrum. How can we do that? What is the parameter in IFEFFIT that allows one - as in Athena - to add a constant number and shift the plot? Stefano PS: needless to say that we are learning... -- ____________________________________________ Stefano Ciurli Professor of Chemistry Laboratory of Bioinorganic Chemistry Department of Agro-Environmental Science and Technology University of Bologna Viale Giuseppe Fanin, 40 I-40127 Bologna Italy Phone: +39-051-209-6204 Fax: +39-051-209-6203 "Fatti non foste a viver come bruti, ma per seguir virtute e canoscenza" Dante Alighieri - Inferno - Canto XXVI "Ihr seid bestimmt, nicht Tieren gleich zu leben, Nein, Tugend zu erringen und Erkenntnis" "Ye were not form'd to live the life of brutes, But virtue to pursue and knowledge high"
