| Abstract: | EPR and optical absorption studies of Dioptase have been carried out at room and low temperatures. The observed, absorption bands have been attributed to Cu2+ ion in C4V symmetry. From the g-values, the ground state of Cu2+ is found to be 2B1. The octahedral and tetragonal field parameters and the spin-orbit reduction parameters have been evaluated. The NIR and IR spectra have also been reported. |
