Dear Neil, Sorry this may be too exact an interpretation of your English, but if you are looking at the exafs then calibration is normally pretty irrelevant as long as it is not wildly out, as you refine E0 anyway in the fitting. The bond distances will be very little altered by this.
If you are looking at XANES and it is 3/4 then CeL3 as I am sure you know has two "white lines" for four and one for three and the ratio of the two peaks can be used to Look at oxidation state mixtures, I think you should be able to align the peaks and fit the area e.g. Burnham AD, Berry AJ, 2014, The effect of oxygen fugacity, melt composition, temperature and pressure on the oxidation state of cerium in silicate melts, Chemical Geology, Vol:366, ISSN:0009-2541, Pages:52-60 Best wishes Fred -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
