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
