Abstract

The fluorescence and phosphorescence spectra were obtained from three coumarins and three linear furocoumarins in n-alkanes at 7 7 K according to Shpolski's method. The substances studied were coumarin, citropten, 5 geranoxy 7 methoxy coumarin; oxypeucedanin glycol, iso-oxypeucedanin and isopimpinelin Coumarin exhibited line-like spectra in fluorescence but the others did not. All substances exhibited fine estructure spectra in phosphorescence, and a vibrational analysis was carried out. The C = C double bond vibration was present in all spectra at 1520-1600 cm-1.
