Three new isomers of [C2H6O]+˙: The radical cations [CH3O(H)CH2]+˙, [CH3CHOH2]+˙ and a low‐energy isomer of unassigned structure

Abstract Three new [C 2 H 6 O] + ˙ ions have been generated in the gas phase by appropriate dissociative ionizations and characterized by means of their metastable and collisionally induced fragmentations. The heats of formation, Δ H f 0 , of the two ions which were assigned the structures [CH 3 O(H)CH 2 ] + ˙ and [CH 3 CHOH 2 ] + ˙ could not be measured. The third isomer, to which the structure $$ {\rm CH}_{\rm 2} = \mathop {\rm …
