Dear collegues

I need the XAFS or XANES spectra for some material to use them in my analysis. Actually, I am not sure if there is a library for the XAFS spectra for different compounds available free online !. In fact, I need the spectra for the following elements and their oxides with different oxidation states as well

1- Ni

2- Fe

3- Mo

4- V

5- Co

6- Mn

Thank you in advance for your help.

Best regards
