Abstract

The Jahn-Teller effect in the EPR spectra of Rh²⁺ and Pd³⁺ in the octahedral configuration of MgO is reported. The dominant structure at 77°K is an isotropic spectrum. At lower temperatures between I.8° and 20°K two types of spectra were observed-an isotropic one which decreases in intensity with decreasing temperature and an anisotropic, tetragonal spectrum, characteristic of three ions per unit cell, that increases in intensity with decreasing temperature. The line shape of the anisotropic spectrum is consistent with a strain-split ground state.
