Respected Sir,

 

            I am new in the field of EXAFS. I have few questions regarding to IFEFFIT i.e., fitting of theoretical models to the  experimental EXAFS data.

1.       What is the ideal value of R- factor for any fit.

2.      Can we use (fit) the theoretical model generated from square pyramidal structure to EXAFS  data of  octahedral structure by assigning degeneracy of 2 for the apical atom. OR using octalhedral for square planar by not using apical path

 

Yours faithfully
