本文用d~4 电子系D_(2h)点群不可约表示对应的强场能量矩阵计算了二氯化铬单晶中Cr~(2+)离子的电子光谱。其理论计算值与观测数据基本一致。因此,二氯化铬中Cr~(2+)离子处在D_(2(?))点群对称的配位场态假设优于Ross-einsky(?) 的D_(4h)假设。
In this paper, the electron spectra of Cr2 + ions in CrCl2 single crystal were calculated using the corresponding strong field energy matrix of d2 (4h) d2 (2h) point group irreducible. The theoretical calculated value and the observed data are basically the same. Therefore, the group symmetry coordination state of Cr2 + ion at D 2 (?) Is better than that of Ross-einsky (?) D 4h hypothesis.
