摘    要：本文论述了油酸铜配合物的ESR波谱和IR光谱,研究结果表明:在油酸铜配合物中存在轴对称性,Cu-O键不仅具有离子性特征而且具有相当大的共价性特征。应用量子化学的多重散射X_α(MS-X_α)方法计算[CuO₄]原子簇,理论计算的g值与实验值相接近。

Abstract: ESR and IR spectra of copper oleate complex have been reported in this paper. The resultscan show that there exsits a axes symmetry of in copper oleate complex. Cu-O bonds have not only ionic character but also a remarkable bit of covalency. [Cu-O₄] atomic cluster has been calculated by means of X_α method of multiple scattering wave (MS-X_α) in quantum chemistry. The gvalues calculated theoritically are approaching that from experiment measurement.
