Abstract: | ESR spectra of Cu2+ in LiKSO4 have been studied at different temperatures. The measured g-values suggest a rhombic field for Cu2+ ion in the lattice. Optical absorption spectra of the crystal have been studied at room and liquid nitrogen temperatures. From the nature and position of the observed bands, they have been attributed to Cu2+ ions in D2h symmetry. The orbital reduction parameters obtained indicate a substantial degree of covalency in the bonding of the copper ion. |
