The molecular ions from three isomeric cyclanones isomerize to the ethyl‐2‐cyclohexanone ion prior to C 2 H 4 elimination. With D‐ and 18 O‐labelled compounds it is shown by Mass Analyzed Ion Kinetic Energy Spectroscopy (MIKES.) that both isomerization and C 2 H 4 loss are specific processes. By high resolution collisional activation spectra it is shown that the resultant fragment ion [C 6 H 10 O] \documentclass{article}\pagestyle{empty}\begin{document}$ 1^{+ \atop \dot{}} $\end{document} ( m/z = 98) differs in structure from the cyclohexanone molecular ion.
