## Abstract The proton NMR spectra of tetraphenylporphyrin, octaethylporphyrin and the analogous chlorins (7,8‐dihydroporphyrins) are presented, and the chemical shift changes on chlorin formation are interpreted using a ring current model. In these compounds a general 10% reduction in the ring cur

The change in ring current of octaethylporphyrin, meso-tetraphenylporphyrin and phthalocyanine cobalt(II1) complexes with axial amine ligands was studied using a double dipole network model. The porphyrin ring current was found to be highest in octaethylporphyrin but decreased by 5% in meso-tetraphe
