摘要：
The chemical shifts and widths of copper K-edges are reported for some schiff base copper complexes by means of X-ray absorption spectroscopy in which a Cauchris type bend spectrograph has been utilized. The metal-ligand distances have been computed using Levy's method. The results arc examined to understand the nature of metal-ligand bonding. The observed linear relationships between chemical shifts (E, eV) and bond distance/(angstrom) and edge width and metal-ligand electronegative differences have been interpreted in terms of changes in the degree of covalency of the metal-ligand bonding in the synthesised copper complexes.
