Tautomeric phenol and 1,3-cyclohexadien-5-one radical cations exist as distinct, stable species in the gas phase.This is established by a study of the photodissociation spectra of C6H6O^+. ions generated from four sources.Specifically, the ionized phenol and the C6H6O^+. from phenetole exist principally as the phenol structure.On the other hand, C6H6O^+. generated from bicyclo<2.2.2>oct-2-ene-5,7-dione and 2-phenoxyethyl chloride exist as a mixture of keto and enol structures.
