Dear everyone,

I am trying to probe the coordination environment of arsenate adsorbed on iron oxide. I got some XAFS data. My question is if the number of Fe atoms arsenate coordinates with influence the edge position of arsenic. Could anybody provide some theoretical explaination to me or some references?

Thanks in advance.

Best regards,

Shaofeng
