Notes:
13C NMR data for several linear furanocoumarins are reported. The β, γsyn and δ effects of a 5-oxygenated function on the coumarinic skeleton were measured. A spectroscopic criterion for distinguishing between C-5 and C-8 oxygenated, between C-5 oxygenated, C-8 alkylated and C-5 alkylated, C-8 oxygenated linear furanocoumarins and between C-5 oxygenated linear or angular furanocoumarins is proposed.
