The mass spectra of endo , endo ‐1,2,3,4,4a,5,8,8a‐octahydro‐1,4:5,8‐dimethanonaphthalen‐anti‐2‐01 (Ia) and its endo , exo ‐2‐ol (IIa) and endo , exo ‐10‐ol (IIIa) isomers have been examined. Fragmentation schemes have been constructed on the basis of metastable transition measurements, accurate mass determination and deuterium substitution. A presence of the double bond in the molecule and a favourable hydrogen atom orientation in the vicinity of the double bond play an important role in the ion degradation process.
