The 13Cchemicalshifts and 13C1H coupling constants of some methoxycoumarins are reported. Some earlier spectral assignments, including those for citropten (limettin), require revision. Methoxy substituent effects on longrange 13C1H couplings in coumarins are highlighted. Peri‐proximity effects for the methyl‐methoxy and methoxy‐methyl couples are derived, and the value of these effects in the assignment
