摘要：

The absorption spectra of a mono tetrahydrofuran adduct derived from tris(bis(trimethylsilyl)amido)neodymium(III) have been recorded at room and at low temperatures. From the spectra obtained a truncated crystal field splitting pattern is derived, and simulated by fitting the free parameters of an empirical Hamiltonian. For 76 assignments a reduced r.m.s. deviation of 26.5 cm(-1) is achieved. The parameters derived allow the construction of experimentally-based non-relativistic and relativistic molecular orbital schemes in the f range.
