Orange Book Entry
An ion formed by interaction of a molecule with a proton abstracted from an ion, as often happens in Chemical Ionization according to the reaction M + XH+ → MH+ + X. The symbolism [M+H]+ may also be used. The widely used term 'Protonated Molecular Ion' is not recommended as it suggests an association product of a proton with a molecular ion.
