The symmetry of the La/sup 6+/ site in LaF/sub 3/ has been determined by x-ray and paramagnetic resonance. The x-ray results show a C/sub 2 nu / site symmetry in agreement with paramagnetic resonance. The optical absorption spectrum shows conclusive evidence of a selection rule contrary to the fact that a C/sub 2 nu / site symmetry gives no selection rule. Hence, there exists a hidden selection rule. (auth)
