Dear All 

Firstly, I would like to say sorry if I have missed out on this discussion before but it would be great if you could help me out. 
I have been analyzing some Mn K-edge XAS data for some battery materials. While the XANES data shows no shift in the main absorption peak which means that there is no oxidation change happening, however, when I am fitting the data in Artemis, I can see a shift in the bond lengths suggesting an oxidation change. Is it possible that bond lengths change even though XANES spectra show no change? 


Thank you and Kind Regards
