Abstract

The nuclear magnetic resonance of 59Co in a single crystal of Co(NH3)6Cl3 has been investigated at room temperature at 15 kG. Observed quadrupolar perturbations have been analyzed by the method of Volkoff for three orthogonal planes to yield five electric field gradient tensors. The cobalt sites associated with these tensors are nonequivalent. The quadrupole coupling constants and asymmetry parameters vary from 1.0 to 17.2 MHz and 0.10 to 0.57 respectively. One of the principal axes of each tensor is found to coincide with the crystallographic b axis of the monoclinic unit cell.
