chalcocite magnetic resonance

chalcocite magnetic resonance

    Investigation of copper minerals by NQR , chalcocite magnetic resonance ,O) occur in the structures of low chalcocite CuzS (Evans 1971,wittichenite Cu3BiS3 (Kocman and Nuffield 1973) and skinnerite Cu3SbS3 (Karup-Moller and MakovickyOptical absorption and EPR studies on enargite - ,using electron paramagnetic resonance (EPR) and optical absorption spectroscopy Optical absorption studies of these minerals give rise to ligand field absorption energies, which sensitively reflect the distortion of cubic, octahedral and tetrahedral co-ordinations.
