摘要：

Two sets of isomeric pyranocoumarins and pyranochromones have been studied by both electron impact and collision-induced dissociation. The daughter spectra were obtained by ion trap mass spectrometry experiments. Characteristic fragments were obtained in electron impact that allowed differentiation between the chromone and the coumarin systems. Distinction between isomers in each set was achieved by collision-induced daughter spectra of selected parent ions.
