Hi Jia:
For the first one of the spectra, I chose the shoulder in the derivative
at 4974 instead of the large peak. I consider the lower energy peak to be
a pre-edge feature due to the 3d quadrupole transitions and I generally
don't choose that. If the analysis later tells me that I am
of longer counting
times?

Hi Carlo,
In many transition metal oxide cases like this, what would be the more
proper E0, the position of the apex of the first derivative peak or the
second one that is usually higher than the first peak, or it really
depends? I have seen people using either. In this particular case, it

Hi Siliang:
The first thing is that you have misidentified the edge position. Itis way
too high in all the data sets.
Put it at the inflection point of the main rise in the absorption

Dear all,
I am new to XAFS data analysis. Im currently working on the XAFS data of
atomic layer deposited mixed oxide thin film: SnTiOx. I have both Sn and Ti
K edge data, and was able to fit Sn edge using a model of (Sn,Ti)O2 solid
solution. However, Ti data really confuses me (please see
