✦ Synopsis

The 'H NMR spectra of variously annulated pyranocoumarins are reported. The complete assignment of chemical shifts was achieved by using coupling constants and the shift effects induced by the introduction of methyl groups at various positions on the pyranocoumarin nucleus, and by comparison with the spectra of known compounds.
