Abstract

The symmetry of the ${La}^{+ 3}$ site in La $F_{3}$ has been determined by x-ray and paramagnetic resonance. The x-ray results show a $C_{2 v}$ site symmetry in agreement with paramagnetic resonance. The optical absorption spectrum shows conclusive evidence of a selection rule contrary to the fact that a $C_{2 v}$ site symmetry gives no selection rule. Hence, there exists a hidden selection rule.
