A Theoretical approach for studying the structure of copper (II) amino acid complexes have been carried out using extended X-ray absorption fine structure (EXAFS). The fine structure of the complexes was done for six copper (II) amino complexes. The theoretical bond lengths of the complexes were calculated by using interactive fitting of EXAFS using fast Fourier inverse transformation (IFEFFIT) method. This method is also called as Fourier transform method. The Lytle, Sayers and Stern method and Levy’s method have been used for determination of bond lengths experimentally of the studied complexes. The results of both methods have been compared with theoretical IFEFFIT method. On comparing the results, the theoretical approach is also described in the present publication.

Keywords :
