Abstract: Near edge X-ray absorption fine structure (NEXAFS) covering energy range up to about 50 eV have been studied. The present studies include some copper (II) complexes of biological interest with 3-arylazo-7-hydroxy-4-methylcoumarin as ligand. Studies have been carried out on Seifert X-ray generator and Cauchois type bent crystal X-ray spectrograph of 0.4-m radius. The observed X-ray parameters e.g. chemical shift, shift of principal absorption maximum, edge-width, fractional oxidation number and percentage covalency have been used to explain the structure of the complexes and these parameters have also been correlated with earlier chemical studies.
