摘要：

The absorption, magnetic circular and linear dichroism (MCD and MLD) spectra, between 5000 and 16000 cm-1, corresponding to the 2Eg to 2T2g 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 D2h 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.
