摘要：

Electronic Raman scattering and absorption spectra are presented which allow an interpretation of the vibronic structure of the T8g (2T1g) excited electronic state of IrF6 at 1.6 µ. Large splittings and shifts are observed for the Jahn-Teller active v2 (eg), v5 (t2g), and 2v5 vibrations. From these spectra linear (D2 and D5) and quadratic (Q2 [a1g], Q2 [eg], Q5 [a1g], Q5 [eg], Q5 [t2g]) Jahn-Teller parameters can be determined. These data are compared with parameters previously obtained for the ReF6 ground state and the IrF6 T8g (2T2g) state at 0.6 µ. © Taylor & Francis Group, LLC.
