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 the chi(k) data with each other, when they oscillate at a
different frequency?
