Hi,
could say more precise what kind of energy shift you are talking about? the position of the white line or the Enot in Artemis. How big it is? Which version of Feff do you use? What do you mean writing "removing background carefully"? Background in the EXAFS fit? Any pictures to illustrate problem are welcome

Hell all
I have the study for PtO nanoparticles with EXAFS.
When I fitted the data to model, I had a problem for energy shift.
I thought that the energy shift obtained from fitting must be below White line. However it was over white line.
Although I removed background carefully and changed bond length in model, the energy shift was still big.
I want to know other factors which affect energy shift.
