✦ Synopsis
A series of novel pyranocoumarin derivatives were analysed by electron impact mass spectrometry and tandem mass spectrometry at low and high collision energy. The collision-induced decomposition tandem mass spectra of the [ M -CH, 1 + ions yielded several structurally valuable fragments and those of the [ M -CH, 1 2 + ions allowed some cbarge-separation reactions to be recognized.
