[Ifeffit] inquire for the EXAFS of the mixture of species

["Dr. Dariusz A. Zając"]

Hi winejia,
it is trivial but at the same time hard problem to solve.
There are 2 ways: using Athena and using Artemis
Using Athena you have measured your sample and all possible references. 
The result comes from the fit of the linear combination of your references.
Using Artemis is similar but instead of measured references you create  
models (FEFF cards) from known structures and than fit to your 
experimental data.
For sure you will find some more tricks in the archive of this mailing 
group.
good luck
