Abstract

Under the combined influences of a strong octahedral crystal field and a large spin-orbit interaction, the $t 2 g 3$ configuration of $R e +4$ , a $5 d 3$ ion, is split into the following states in order of increasing energy: $U g' (4 A 2 g), U g' (2 T 1 g), U g' (2 E g), E g' (2 T 1 g), E g'' (2 T 2 g)$ and $U g' (2 T 2 g)$ . Electric dipole forbidden transitions between the $U' (4 A 2 g)$ ground state and all these excited states have been observed directly for the first time in cubic crystals of $C s 2 Z r C l 6 : R e +4$ and $C s 2 Z r B r 6 : R e +4$ by means of low temperature absorption and magnetic circular dichroism (MCD) spectroscopy. The assignments are confirmed via a hot band analysis of the 77K absorption and MCD spectra. The experimental results will be compared to the results of a ligand field calculation.
