## 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
