Hi all
I have a question for XANES of Zinc compounds.
It is known that the pre-edge for Zinc K-edge generally doesnt exist because 3d state of Zinc atom is occupied.
However, I got it from ZnMgO with wurtzite structure. 4 oxygen in first shell and 12 zinc in second shell are located around Absorbing atom, Zinc in wurtzite structure.
And then I know that some Mg atoms are replaced on zinc site from EXAFS.
I wonder the reason for the appearence of pre-edge. Is it structural problem? or substituted Mg?
If anybody know reference papers for pre-edge of zinc K-edge, Please answer me.
