Summary
The positions of the signals from the C3, C5, C6, and C7 carbon atoms in the13C NMR spectrum of coumarin have been established with the aid of information obtained from the13C NMR spectra of [3-D]-, [4-D]-, and 7-methoxycoumarins and by the use of an additive calculation based on the increments of the methoxy group in the13C NMR spectrum of anisole.
