Dear Christopher, Dear Scott, Thank you so much for your valuable feedback. I will now attempt to quantify the observed change in amplitude ratios by fitting data with theoretical standards.

For example, I have a sample which is measured at various states, say A, B, C, D and E during any physical or chemical process. I get systematic change in the ratio of first two peaks at each state. This could be interpreted either as change in disorder or as change in number of atoms associated with first two shells as a result of any physical or chemical change material has undergone. As we know that amplitude of peak decreases with increase in distance from central absorber. Can I compare the amplitude ratio of first two peaks for various states of same sample ?? Many thanks in advance !!!
