摘要

The absorption spectra (in the IR/NIR/Vis/UV range) of Ce(C5Me4H)(3) (1) and La(C5Me4H)(3) (2) were recorded at room and low temperatures. From the spectra obtained, two alternative closely related crystal field (CF) splitting patterns of 1 could be derived, and simulated by fitting the free parameters of a phenomenological Hamiltonian. The fact that the difference of the experimental energies of the barycenters of CF levels of the multiplets F-2(7/2) and F-2(5/2) is larger than in the gaseous free Ce3+ ion ("anti"-relativistic nephelauxetic effect) could be explained by coupling effects of these multiplets via the CF, resulting in lower spin-orbit coupling parameters than in the case of the gaseous free Ce3+ ion. The experimentally derived CF splitting pattern of 1 is compared with the predictions of previous non-relativistic SW-X alpha and relativistic DV-X alpha calculations.
