The collision‐induced dissociation reactions of the [M1] − and [M3] − ions of cyclopentanol, cyclohexanol, cyclopentanone, cyclohexanone, cyclopent‐2‐en‐1‐one and cyclohex‐2‐en‐1‐one have been studied under lowenergy collisional activation using a Fourier‐transform ion cyclotron resonance mass spectrometer, and compared to literature data obtained at lhigh‐energy and under single‐collision conditions. Some significant differences appear in these data, which are discussed. Moreover, a general scheme of fragmentations appears between the alcohol, ketone and enone functions.
