✦ Synopsis

The 54.2 MHz I7O NMR spectra of a series of naturally occurring coumarins and furocoumarins and those of a number of related model compounds are described. The ''0 chemical shifts of the furocoumarins can be predicted by the evaluation of the data of substructures in model compounds. syn-Periplanar y -and long-range interaction effects can be interpreted in terms of steric and electronic effects.
