Electronic and vibronic energy levels of the (dt2g)2 configuration of OsF6 are studied using electronic Raman scattering and absorption spectroscopy. The ground state has been identified as Eg (crystal field split by ∼28 cm-1) and the first excited state is T1g with crystal energy levels at 14, 28, and 40 cm-1. The three other regions of the spectrum that have been observed are at 4000 cm-1, 8000 cm-1, and 17 000 cm-1 covering the remaining (dt2g)2 configuration leveIs. The 4000 cm-1 band consists of A1g and T1g electron states which do not interact strongly through vibronic coupling. The T1g electronic state evidences a strong (D∼2·2) linear Jahn-Teller effect for ν5 and an observable Jahn-Teller effect for ν2. The band at 8000 cm-1 consists of Eg and T2g electronic states; it is so complex and strongly coupled that little information can be extracted from the absorption data concerning the Jahn-Teller interaction in this 5-fold degenerate manifold. The feature at 17 000 cm-1 is an A1g electronic state and its elucidation follows normal behaviour found in other hexafluoride spectra. |
