作为文献[4]的自然推广,本文讨论了低对称性(C4v或D4h,C3v或D3h)晶场中3d5离子零场劈裂常数D值的计算。给出D值依赖于Racah参数、晶场参数和自旋-轨道耦合常数ξ的表示式。用于α-Al2O3晶体中Fe3+,离子D值的计算,结果与实验值能够较好地符合。As a natural extension of work [4], in this paper the calculation of zero field splitting parameter D of 3d5 ions in low symmetry ( C4v or D4h,C3v or D3h ) crystal field is discussed. The expressions of parameter D in terms of Racah parameters, crystal field parameters and spin-orbit coupling constant ξ are obtained. Applying to Fe3+ in α -Al2O3 crystal, the calculated result agrees fairly well with the experimental value.
