X-ray absorption fine structure studies of some copper (II) complexes

X-ray absorption fine structure studies of some copper (II) complexes have been done using Seifert X-ray generator and Cauchois type bent crystal X-ray spectrograph of 0.4 m radius. It has been shown that the graphical method originally proposed by Lytle, Sayer and Stern gives useful information about the bond length and also the environment of the absorbing atom. While the phase parameter of the first coordination shell alpha(1) and beta(1) provide valuable information about the forward and back scattering atoms, respectively, the total phase shift delta(1) gives an idea about the periodicity of the X-ray absorption fine structure. It has also been shown that the periodicity is affected by the presence of different ligand in the studied copper (II) complexes.
