Hi all, First of all, I would like to thanks Anatoly for his file and everybody for useful comments. I have analysed Anatoly's data and I have obtained a good value for S02 = 0.85 or 0.82 (depending on the number of variables used). So, my data is the problem, and it is not my analysis, but maybe my measurements need a more accurate analysis with Athena as Scott suggested. I was not at synchrotron measuring platinum samples and I only know that are measured in fluorescent mode. As Bruce said, I have no beamtime now for more measurements.
I have more questions, related and not related to the last subject, but I am still thinking about them: The first one is easy, it is about the Nyquist theorem. I read in a paper that the formula is 2·deltak·deltaR/pi + 2. The last "+2" is new for me and I am afraid that Artemis does not consider it. I am sure that it is a silly thing. I will try to correct again Ptfoil considering self-absorption in order to obtain a spectrum similar to Anatoly's or Bruce's one. And then, I will apply the same correction for supported platinum catalysts, right? I also observed that Anatoly's Pt foil shows good signal even for large k (20 A-1). Nevertheless, obviously platinum catalysts spectra possess lower signal and specially for high values of k where the noise is big. The question is, despite Pt foil has a good signal until 20 A-1, it is usually used a smaller k-range (i.e. 3-12 A-1), right? I normally use a k-range of 3-12. And finally, how to calculate bond distances from Reff and deltaR? Thank you very much Best regards, JA
