N2 - C6H6+. ions from different neutral precursors were studied by photodissociation and by reactions with 2-propyl iodide and hexadeuterobenzene in rapid scan and Fourier transform ion cyclotron resonance spectrometers. Ejection of all ions from the ICR cell, except ions of one particular mass, proved to be essential for the ion/molecule reaction studies. From those studies it was concluded that fulvene ions are stable towards isomerization, whereas C6H6+. ions from 1,5-hexadiyne have the benzene structure. In all other cases, a mixture of at least two or three (for dimethylene cyclobutene) different ion structures was found. One of these ion structures corresponds to the structure of the parent neutral molecule. Also, in all cases, part of the ions isomerize to a non-photodissociating structure. The experimental results indicate that these ions have the benzene structure.
