Re: [Ifeffit] Question about EXAFS fitting of mixtures

That question reminds me of a Russian riddle: In each corner of a room there is a cat. In the eyes of each cat there are three cats. On the tail of each cat there is a cat. How many cats are there? Anatoly

 Dear all,

While fitting EXAFS for tiny Pt nanoparticles, a simple question occurred to me. For these two scenarios: 1. All Pt atoms are coordinated to 3 O atoms and 3 Pt atoms each. 2. Half of the Pt atoms are coordinated to 6 O atoms and half to 6 Pt atoms.

If we fit only single-scattering paths, would it be possible to tell apart these two scenarios with EXAFS fitting? What about linear combination analysis of the XANES?

Thank you, Soyoung
