We have Cr doped composite material sintered at different temperatures and utilized XAFS beamline at Synchrotron to investigate oxidation state and structural changes, we have Cr(III) and Cr(VI) standard files but missing Cr(O), Cr(I), Cr(II) standard data files.
Dear Sajid Iqbal ,
for Cr(0) please see for example Fig. 2 of:
Article X-ray absorption characterization of Cr in forsterite within...
You may ask the authors for the data file.
Also fig. 2 of the following paper could be helpful:

Dear Sajid Iqbal ,
Artur Braun is right,
they have dealt with Cr oxidation states.
Two of them are RG members.
Please see the following link to have access to their RG pages.
You should look into their papers.
Good luck....

Hi Sajid,
For sure in the database of the XAFS beamline we have something that could be useful to you. If you are interested, write to me a private message.
Best regards
Simone
PS An alternative could be to "digitalize" spectra from diagrams reported in the literature using the free online tool https://automeris.io/WebPlotDigitizer/
Hi Sajid,
You may encounter some reference spectra in:

Good luck
