Dear all,
I have the EXAFS data at 800'c that shows disorder phase but the E(ev)-Xµ(E) graph shows similar peak with the crystalline phase. Also, I seen in the in-situ XRD that at 800'c my structure is amorphous. Is that possible the liquid phase ( amorphous) have a similar peak with crystalline phase in the E(ev)-Xµ(E) graph?
I appreciate you help and your time in advance.
Dear Hadi,
you may share what type of sample you deal with.
With respect to EXAFS of solid and liquid samples I would expect that first shell peaks (in FFT) would remain at the same position when going from the solid to the liquid phase because these positions are due the nearest neigbour bond lengths in a molecule, but for liquid state I would expect a strong decrease of 2nd and and very strong decrease (up to total absence) of higher order shell contribution due to the amorphous character of liquids ( lack of medium to long range order).
