[Ifeffit] How to identify N and O atoms in the first coordinate

[mzhu at udel.edu]

Hello all,
  Merry Christmas!
  I have some samples of heavy metal sorption on bacterial biofilm. I want to figure out what elements are coordinated with the heavy metal in the first coordinate. Since the oxygen and nitrogen have similar scattering factors, how can I differetiate them? Using shell-by-shell fitting or linear combination fitting with standards? Thanks.

Best wishes,

Mengqiang Zhu
