四面体四角晶位中络离子CoX_4^(2-)(X=Cl,Br)g因子的研究

INVESTIGATION OF THE g FACTORS FOR CLUSTERS CoX_4^(2-) (X=Cl,Br) AT THE TETRAGONAL CRYSTAL FIELDS

用双自旋 轨道耦合参数模型研究了四面体四角晶位中络离子CoX2 -4 (X =Cl,Br)的g因子 .研究表明 ,配体Br对Co2 +离子g因子的影响不能忽略 .

The EPR parameters g factors at the tetragonal clusters CoX 2- 4(X=Cl,Br) are studied by means of a double spin orbit (SO) coupling parameter model.The theoretical results agree well with experimental findings.The investigation shows that the contribution from the ligands Br to EPR parameters g factors of the Co 2+ ions can not be neglected.
