The 13C-nmr spectra of variously annulated methylfurocoumarins are reported.The assignemnts of chemical shifts for all the C resonances has been achieved by using carbon-proton coupling constants, relaxation efficiency considerations and shift effects caused by the introduction of methyl groups at various positions of the furocoumarin nucleus.Substituent effects on 13C chemical shifts and carbon-proton coupling constants are discussed.
