13C NMR data for several simple coumarins are reported. The ysvn effect of a 5-methoxy substituent on the C-4 chemical shift was observed and measured. The effects of an 8-iodo substituent on the chemical shifts of the carbons of the coumarinic skeleton are discussed.

## Abstract ^13^C NMR data of nineteen coumarins, twelve of which bear a prenyl (isoprenoid) side‐chain at C‐3, are reported and compared with those of the C‐3 unsubstituted compounds. Unlike the linear isomers, no γ‐effect is observed in the corresponding angular derivatives; this is proposed as s
