Hi for all,

I am trying to fit an EXAFS data for TiO2 that is mainly in anatase form with a small quantity of rutile, accordingly with XRD. The material was produced by chemical route.

I would to show that Ti-O1, Ti-O2 and Ti-Ti1 suffered a decrease in the coordination number. Both in R and q space the fit is not very good for Ti-Ti1, like if missing something?

I think that I should introduce oxigen vacancies to improve the fit, but, it is right? If so, how to make it?

Thanks for all.
