摘　　要：在晶体场理论基础上,推导出了3d9离子在压缩四角对称晶场中2B1g态混合进基态2A1g的EPRg因子的三阶微扰公式.用该公式研究了晶体3Cu(IO3)2.2H2O中Cu2+离子两种占位的EPRg因子,并分别计算了它们的电子吸收能级,理论研究合理地解释了实验结果.On the basis of the crystal field theory, the formulae of the d-d electronic energy levels and EPR g -factors within thirdorder perturbation for 3d^9ions in the compressed tetragonal field have been obtained. The mechanism for an admixture of the ^2Blg into 2Alg （ pound state ） is introduced. Using these formulae, the d-d absorption spectra and EPR g -factors for two crystalline sites of Cu2. ions in 3Cu（IO3） 2·2H20 crystal have been investigated. The theoretical calculations are in good agreement with the experimental observations. Absorption spectra and EPR g-factors are reasonably explained.
