假设在晶体Na_2ZnCl_4·3H_2aO:Mn~(2+)中,处于C_3轴上的一个Cl~-被一个O~(2-)取代,形成MnOCl_3基团,利用对角化能量矩阵的方法,计算了该晶体的电子顺磁共振(EPR)参量D,(?)和g(?)因子,以及单轴压力效应dD/dp和da/dp,得到与实验一致的结果,表明上述假设是合理的.In present paper, we proposed a new assumption that the O2- ion replaced the Cl- ion on the trigonal axis. On this basis, the EPR parameters D, a and gn were calculated. The results agree well with the experiments. The effects of uniaxial stress dD/dp and da/dp were also explained. This indicated that the assumption is reasonable.
