Dear Shaofeng,

You really do need to fit to know for sure. Aside from changes in bond length, there are many other effects that can shift a peak.

Dear all experts,

I am processing two As K edge EXAFS data  shown as following figure. The first shell is As-O. The difference of the As-O peak btween sample As1 and As2 is around 0.03A. Does this represent that the average As-O bond length of sample As1 should be around 0.03 A longer than that of sample As2? Or this depends on fitting results ?

Any help is very appreciated.
