Abstract
Calculations have been made of the likely ionic distortions caused by incorporation of the Tm2+-H-(s) trigonal centre in the CaF2, SrF2 and BaF2 lattices. The resulting trigonal contributions to the crystal field are calculated using a scaled point charge model and compared with experimental values derived from the g value anisotropies, assuming the A20(r2) distortion to dominate.Keywords
