Codruta - it's better off if you have someone walk you through this type of analysis for the very first time, as it is somewhat involved. You may decide to come to one of the short courses (the nearest ones will be at the APS in the end of July, and the NSLS in October - the dates are still being finalized), or collaborate with someone experienced on the list. As Scott Calvin is reasonably close to Yale, he may be your best bet. If you are willing to expand your radius and travel to Brookhaven for a few days, my postdoc Adele Wang could help too.

Recently I have performed some analysis at the NSLS. It is clear from the spectra in R space that the interatomic distances are modified compared to the monometallic catalyst therefore I am dealing with an alloy. Does anyone have or know about a model that would allow me to get a coordination nomber using Artemis. Thank you, Codruta. _______________________________________________ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit
