## Abstract The proton NMR spectra of tetraphenylporphyrin, octaethylporphyrin and the analogous chlorins (7,8βdihydroporphyrins) 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

## Abstract The equivalent dipole model of the ring current shift in benzene is shown to be equivalent to that of the wellβknown two current loop calculation. A network model of the ring current effect in the porphyrin system is described, using the doubleβdipole approximation, to give a calculatio
