Abstract The structures of the [MOH] + ions of m ‐ and p ethylnitrobenzene have been compared by measurements of metastable ion spectra, collisional activation spectra, kinetic energy releases and critical energies for the formation of these ions and their subsequent decomposition. Normalized rates of fragmentation of metastable molecular ions and metastable [MOH] + ions have been compared for ion lifetimes up to 30 μs. The energy measurements fail to distinguish between the structures of the [MOH] + ions, but the normalized fragmentation rates and the collisional activation spectra show their structures to be different.
