The energetics and mass spectral characteristics of a number of [C 7 H 5 ] + ions have been examined. No compelling evidence could be found to show that the 2‐cyclopropaphenyl cation was produced by loss of bromine from the ionized 2‐bromo derivative. It was proposed that the ethynylcyclopentadienyl cation may be the global minimum on the [C 7 H 5 ] + hypersurface.
