K-Absorption Spectral Studies of Some Mixed Ligand Copper Complexes Using Synchrotron Radiation

X-ray absorption fine structure (XAFS) at the K-edge of copper has been studied in some copper mixed ligand complexes having hydroxamic acid as one of the ligands. The study can be used to yield useful and important information about the molecular structure of the complexes. The X-ray absorption measurements have been performed at the recently developed BL-8 Dispersive EXAFS beamline at 2.5 GeV Indus-2 Synchrotron Source at RRCAT, Indore, India. The data obtained has been processed using EXAFS data analysis program Athena. The normalized EXAFS spectra have been obtained and Fourier transformed to extract information about first shell bond length. The first shell bond length has also been obtained using graphical method of data analysis and compared with that obtained using Fourier transform method.
