摘要

Abstract A model of the paramagnetism in cobalt (II) porphyrin complexes has been developed which successfully calculates paramagnetic shifts for protons not affected by the contact term. The model utilizes a single large dipole positioned on the cobalt (II) atom, and calculates the pseudo-contact shift using the dipole approximation.
