Determination of bond lengths from EXAFS spectra using different methods

The EXAFS spectra have been recorded at the K-absorption edge of copper acetate (Cu (CH3COO)2 on a bent crystal 0.4m Cauchois type transmission spectrograph employing a mica crystal oriented to reflect from (100) planes for dispersion. EXAFS maxima and minima positions have been obtained. The bond length have been determined using four different methods, i.e., Levy's, Lytle, Lytle, Sayers and Stern's (LSS) and Fourier transformation methods. Both LSS and Fourier transformation methods give phase uncorrected bond lengths and hence results obtained from them have been compared with each other.
