Single crystals of cupric 3hyphen;pyridine sulfonate diluted in the diamagnetic zinc compound were prepared and observed for paramagnetic resonance. The symmetry of the magnetic complex is orthorhombic, with two of thegvalues only slightly different. The ground state of the ion isdz2 which exhibits practically no orbital angular momentum alongz. An analysis of the cupric hyperfine structure at room temperature has been performed, arriving at a value of the polarization of the core in very good agreement with the theoretical estimate. No nitrogen superhyperfine structure is resolved at room temperature, although experiments at 77deg;K show conclusively interaction with two equivalent nitrogens, which is interpreted in detail.
