Visible and near IR absorption spectra of mixed crystals of $IrF_{6}$ in $UF_{6}$, $WF_{6}$ or $MoF_{6}$ at $2.2^\circ K$ have been taken. Vibrational and electronic Raman work has been done. The $t_{2g}$ vibration in the degenerate $\Gamma_{8}(O^{*}_{h})$ state at 0.68 microns has been reassigned on the basis of its combinations. The implications of this reassignment are discussed in terms of Jahn-Teller and vibronic coupling models. Comparisons are made with results obtained for the degenerate $\Gamma_{8}$ state at 1.64 microns and the Kramers^{\prime} $\Gamma_{7}$ state at 0.83 microns. en_US dc.format.extent 91342 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE JAHN-TELLER EFFECT IN $IrF_{6}$ en_US dc.type article en_US
