A mass spectrometric study of six new a-methylene-y-lactone carbohydrate derivatives has been carried out in order to correlate the occurrence of metastable transitions with the stereochemistry of the compounds. Results indicate that the decomposition of some metastable fragment ions usually release
## Abstract The electron‐impact‐induced decomposition of the title compounds has been investigated in detail. Deuterium labelling was used to study the mechanisms of fragmentation and the structures of ions generated. Hydrogen, methyl and phenyl group migrations to one of the silicon atoms were obs
## Abstract Electrospray ionization tandem mass spectrometry (ESI‐MS/MS) was used to investigate the fragmentation pattern of ten sesquiterpene lactones of the goyazensolide type under low‐energy collision‐induced dissociation (CID) using a triple quadrupole mass spectrometer. The analysis revealed
