Abstract
In a previous paper1 it has been shown that C2H3O+ ions generated from different compounds isomerize to a common structure (or mixture of structures) prior to decomposition in the field-free region of the mass spectrometer. In the present work metastable transitions of12C13CH3O+ ions generated from acetone-2-13C are investigated, in order to find out if the isomerized structure is cyclic or linear. The results are in agreement only with a linear structure, about 8% of the ions showing migration of oxygen prior to decomposition. Isomerization to acetyl cation is assumed.
