The cis-and trans-annulated isomers of 8-(N-pyrrolidyl)bicyclo[4.3.0]nona-3,7-diene show different propensities for the retro Dieis-Alder fragmentation following electron impact ionization. Molecular ions of the cis-annulated isomer decompose predominantly via the retro Diels-Alder reaction to give

## Abstract The mass spectra of the title compounds differ considerably depending on the annulation of the bicyclic skeleton. For a series of alkyl derivatives the __cis__‐annulated compounds show a higher abundance of the products due to the retro Diels‐Alder cleavage than the corresponding __tran
