摘要
利用d_2(D_(4k))全组态混合统一晶场理论对Ni(pz)_4Br_2型化合物的光谱、基态ZFS,EPR参量及基态顺磁磁化率进行了系统的理论分析与计算,计算结果与实验值符合得甚好,从而对Ni(pz)_4Br_2的光磁性质作出了完整的合理的理论解释,也表明Ni^(2+)离子的局域环境晶场采用D_(4b)对称性是一种极好的近似.
By means of a complete configuration mixing unified crystal field theory ford8(d4h), the optical spectra and the ground state ZFS、EPR paramenters and the ground state paramagnetic susceptibility of the Ni(pz)4Br2 compounds are analysed and calculated theortically and systematically. All results agree well with the experimental data, so as to obtaion a complete and reasonable explanation for the optical and magnetic properties of Ni(pz)4Br2, It is shown that the regional surrounding crystal field of Ni2+ by using D4k symmetry is a very good approximation.
