Abstract

Negative hydride ions can readily be introduced as substitutional impurities into the alkaline earth fluorides. The crystals then possess an infra-red absorption spectrum due to localised vibrations of the hydride ion. In the case of calcium fluoride there is a strong triply degenerate line at 965 cm-1 with associated second and third harmonics.(1)
