Description	Journal: Journal of Physics C: Solid State Physics The absorption, magnetic circular and linear dichroism (MCD and MLD) spectra, between 5000 and 16000 $cm^{-1}$, corresponding to the$ $^{2}$E_{g}$ to$ $^{2}$T_{2g}$ optical transition are reported. The data for a sharp magnetic dipole line assigned to the$ ^{2}$ Gamma$ _{1g}$ to$ ^{2}$ Gamma$ _{4g}$ transition in the $D_{2h}$ site symmetry group are analysed by taking into account the spin-orbit coupling and the Jahn-Teller effect. The in-plane magnetic field dependence of its absorption and MLD are shown to be due to the Jahn-Teller effect giving rise to an alternate disposition of the fluorine octahedra surrounding the copper ions. It also induces a reduction of the MCD as found experimentally. The authors' assignment of the other sharp vibronic lines appearing in the spectra is also given starting from their magneto-optical data.
