用算符等效方法计算了Tm(C2H5SO4)3·9H2O中电子能级3P2、1D2、3F2、3F3、3F4、1G4和3H6的理论分裂。对α，β和γ进行了中场校正。用晶场参数A20<R2>=13 cm-1、A40<R4>=-80 cm-1、A60<R6>=-32 cm-1和A66<R6>=300 cm-1对Tm3+(4f12)进行了一阶微扰处理，得到了与实验合理一致的晶体量子态位置。
The operator‐equivalent method was employed to calculate the theoretical splitting of electronic energy levels 3P2, 1D2, 3F2, 3F3, 3F4, 1G4, and 3H6 in Tm(C2H5SO4)3·9H2O. Intermediate field corrections were made to α, β, and γ. A first‐order perturbation treatment on Tm3+ (4f12) in C3h symmetry, using crystal‐field parameters A20〈r2〉=13 cm—1, A40〈r4〉=—80 cm—1, A60〈r6〉=—32 cm—1, and A66〈r6〉=300 cm—1, predicts the position of the crystal quantum states in reasonable agreement with experiment.
