The magnetic environments of Cu(2+) doped Na(+) complex have been identified by electron paramagnetic resonance (EPR) technique. The angular variation of the EPR spectra has shown that two different Cu(2+) complexes are located in different chemical environments, and each environment contains one magnetic Cu(2+) site occupying substantial positions in the lattice and showing very high angular dependence. The principal g, and the hyperfine structure parameter (A) values of two sets of Cu(2+) complex groups are determined. The covalency parameter, mixing coefficients and Fermi-contact term of the complex are obtained, and the ground state wave function of the Cu(2+) ion in the lattice has been constructed.
电子顺磁共振（EPR）技术确定了 Cu(2+) 掺杂的 Na(+) 配合物的磁性环境。EPR 光谱的角度变化表明，两种不同的 Cu(2+) 配合物位于不同的化学环境中，每个环境都包含一个磁性 Cu(2+) 位，占据晶格中的重要位置，并表现出非常高的角度依赖性。确定了两组 Cu(2+) 配合物的主要 g 值和超精细结构参数（A）值。获得了配合物的共价参数、混合系数和费米接触项，并构建了晶格中 Cu(2+) 离子的基态波函数。
