Dear Ifeffit community, Thanks for your questions. I am very new to this field (M.Sc. student in soil science), so I really appreciate that you are taking the time to give me some advice. I have attached a picture of some of the normalized spectra I am working with as well as mu(E) spectra (I am sorry for attaching the picture, for some reason my email did not allow me to copy it into this message). I am doing Xanes analysis on phosphorus in bone char. My normalization range is from 15-60 eV and pre-edge range is from -13.5 to -6.75. Maybe my normalized spectra looked actually fine; they are not that far above 1 (more or less around 0.3 above). I just thought they looked a little strange/skewed. Let me know what you think. Thanks, Marie
