[Ifeffit] Mathematical expressions for the path parameters in Fitting

2010-09-17 Thread sumitk
Hello, In EXAFS data modeling carried out by fitting excercise, we develop mathematical expressions for different path parametrs as functions of a smaller set of fitting parameters that can be adjusted to achieve to best fit to the data. I am carrying out EXAFS analysis of Eu(III) sorbed on

Hi Sumit: There are a lot of different ways to constrain the EXAFS parameters in a fitting model. Mostly they are determined by physically meaningful relationships or through trial and error of what works. I just sent you my book chapter and you will find detailed discussion on many of the common
