【 摘 要 】

Extended X-ray absorption fine structure (EXAFS) spectra have been recorded at the K-edge of Fe (II) complexes using the energy dispersive EXAFS beam line at 2.5GeV Indus -2 synchrotron source at RRCAT, Indore, India. A theoretical EXAFS data analysis is also carried out by Fourier analysis of experimental EXAFS data of the two iron (II) complexes. This analysis includes details of the Fourier transform of the data and the extraction of metal-ligand bond length. Bond lengths determined from data analysis methods are compared with the bond lengths obtained from several other known existing techniques. These data have also been calibrated by derivative method and bond lengths have also been obtained from Fourier transformation method and the results have been compared with the each other. The EXAFS data have been analysed using the computer software Athena.
