Extended X-ray absorption fine structure data analysis of copper (II) complexes of 6-methl-5-arylhydrazono-2-thio-4-oxo-pyridine ligandy

A technique is presented for Extended X-ray absorption fine structure (EXAFS) data analysis for determining the metal-ligand bond length using conventional source. A theoretical EXAFS data analysis is carried out by Fourier analysis of experimental EXAFS data of some copper (II) complexes of 6-methyl-5-arylhydrazono-2-thio-4-oxo-pyridine. The analysis of EXAFS data is presented using MathCad programming and FEFFIT (Fitting of EXAFS by Fast Fourier Inverse Transform) programming. This analysis includes details of the Fourier transform of the data and the extraction of metal-ligand bond length. Bond lengths determined from these two data analysis methods are compared with the bond lengths obtained from several other known techniques.
