Abstract

Structures of [C6H6]2+ ions formed by electron impact from benzene, 2,4‐hexadiyne and 1,5‐hexadiyne have been investigated by the recently developed electron capture induced decomposition method, by charge‐separation reactions and by ion abundances in electron impact mass spectra. Significant differences were found among the isomers indicating the structural integrity of these [C6H6]2+ ions. The observed differences indicate that the most likely atomic configuration of [C6H6]2+ ions produced from benzene and 2,4‐hexadiyne is the same as in the corresponding neutral species. A new method is suggested by which the structure (atomic configuration) of doubly charged ions may be determined.
