Hello,
First of all, I am still very new to XAS analysis, so please excuse any
misunderstandings I may have.
I have a series of compounds nominally consisting of KxVx[Cr(CN)6] Prussian
blue analogs (where x is ~1) with Cr(III) and presumably V(II) present in
the system. From other evidence, the V
The standard curve using V standard, how are you making the curve? You
probably know from the Wong paper that there are pre edge features for the
vanadium oxide species. We used a very similar method to assign oxidation
states to doped vanadium oxide compounds between 3-5. The method gave us

Matt,
"It can be challenging to extrapolate from XANES with different ligands,
and Prussian Blue with linear CN ligands might act quite differently from O
ligands. Like, I wouldn't necessarily suspect the VS04 was a particularly
good reference for you, though I could be wrong."
I think this is
If you have Dr. Whittaker-Brooks data then you have the work we did on vanadium
oxides. You can look at some of the other vanadium papers we did.

Chris,
It looks like your other vanadium papers all seem to involve vanadium
oxides in different oxidation states. While I think this method works very
well for metal oxides, in my case there should only be isocyanides bound,
from the vanadium perspective (not counting defect sites), so I'm not fu
Hi Adora:
FEFF9 does a pretty good job of calculating XANES now. YOu might want to
try using that to confirm what you think you have. I agree with you that
having an environment similar to your target compound is essential for
calibration of valence.
