Hi Shelly,
Interesting--I've never tried that method with samples that I expect
to differ in oxidation state. If it's differing in oxidation state,
the local environment is probably different too...particularly,
nearest-neighbor distances should be changed significantly. So how do
you align th

Hi Tony,
A quick answer before I try to fight my way through an ice storm to
get to work. :)
Fitting the three spectra simultaneously makes sense, but if
oxidation state is expected to be different, then you really need
different E0's.
As far as doping, it depends on the details. In some case
Hi,
first I would like to thank all experienced people answering in this forum!! I
have learned really a lot from you.
And now my question:
Should I fit EXAFS spectra of a doped material and the same material, but
oxidized and reduced (three spectra) simultaneously? In my opinion: yes, as I
