摘要：

In several recent studies orthogonal correlation-crystal-field (CCF) operators for the f(N) configuration have been used to improve fits to the energy levels of several lanthanide compounds. Here we report results for Sm3+:Na3[SM(oxydiacetate)3].2NaClO4.6H2O. We show that the addition of fourth rank orthogonal CCF operators g2(4), g4(4), g10A(4), and g10B(4) to the Hamiltonian for the 4f5 configuration improves the fit. Our fits are in qualitative agreement with ab initio calculations of CCF effects for lanthanide ions.
