Abstract
The hyperfine structures of submillimeter EPR spectra of CsCdBr3:Tm3and CaF2:Dy2+ single crystals have been resolved and analyzed. The cry stal field parameters and the magnetic hyperfine constants are obtaine d from fitting the envelopes of the simulated spectra to the measured signals. From the specific peculiarities of the hyperfine structure th e energy of the interion interaction in the thulium dimers in CsCdBr3, is determined. The isotopic shift of the crystal field splitting in e nergy patterns of dysprosium isotopes in CaF2 is estimated.
