摘要: The construction of orthogonal operators to represent correlation crystal field (CCF) effects in the f N configuration lanthanide and actinide ions is discussed. approach B. R. Judd [J. Chem. Phys. 66, 3163 (1977)] extended make all orthogonal. spin‐correlated (SCCF) parametrization that has been successful removing several long‐standing anomalies from fits involves only two two‐electron orthogonalized operators. We calculate values CCF parameters recent ab initio results. On basis these calculations sixth rank SCCF are predicted be very important. Fits using various combinations reported for Ho3+ Gd3+in LaCl3. For systems we obtain consistent results associated with SCCF.
