| Abstract: ESR spectra of the copper (Ⅱ) complex with salicylidene aspartic acid Schiff bases in pyridin solvent were investigated at different temperatures.The second order effect and the relaxation effect on the solution ESRspectrum at room temperature were observed and satisfactorily explained.The relaxation parameters were calculated.By using spectral parameters from ESRspectrum at low temperature, the bonding parameters of Cu (Ⅱ) complex were calculated.The bonding characterization and stability of the complex were disscussed.The properlies of the ligand and the complexes of copper (Ⅱ), zinc (Ⅱ), cobalt (Ⅱ) and nickel (Ⅱ) in scavenging O2·- were directly measured by ESR.The results show that the ligand and complexes all have the scavenging O2·- ability, and the inhibition ability of the complexes were stronger than that of the ligand, and the inhibition ability of the copper (Ⅱ) complex was the strongest. |
