Investigation of the Bonding of Iron-Group Ions in Fluoride Crystals. I

Abstract
This paper describes an investigation by ESR methods of the bonding of iron‐group impurity ions with the configurations d3, d5, and d8 in LiF, NaF, KF, KMgF3, and KCdF3. The results indicate that π and σ bonding are comparable in magnitude and provide evidence for the relaxation of ligands on to impurity ions in the alkali halides.
