摘要：

The absorption, magnetic circular dichroism and luminescence spectra of monomeric pseudo trigonal planar (eta(5)-Me3SiC5H4)(3)Pr-III (Cp'Pr) have been measured at room and at low temperatures. Applying the selection rules for molecular D-3h symmetry, a truncated crystal field (CF) splitting pattern (which comprises essentially excited Gamma(4) and Gamma(6) states) could be derived. The parameters of an empirical Hamiltonian were fitted to the energies of 24 levels to give an r.m.s. deviation of 21.4 cm(-1). On the basis of the CF parameters obtained, the CF strength of one Cp ligand was estimated.
