Notes:
A series of novel pyranocoumarin derivatives were analysed by electron impact mass spectrometry and tandem mass spectrometry at low aud high collision energy. The collision-induced decomposition tandem mass spectra of the [M — CH3]+ ions yielded several structurally valuable fragments and those of the [M — CH3]2+ ions allowed some charge-separation reactions to be recognized.
