The loss of CH 3 ˙ from the molecular ions of cyclohexene oxide and 5,6‐dihydro‐4‐methyl‐2 H ‐pyran has been investigated. On the basis of metastable peak shape analysis, collision‐induced dissociation/mass‐analysed ion kinetic energy spectra and thermochemical data it is concluded that the same [C 5 H 7 O] + ion is formed in both cases.
