== [[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<sup>+</sup>  &rarr; MH<sup>+</sup> + X. The symbolism [M+H]<sup>+</sup> 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.

DRAFT DEFINITION
Protonated molecule
An ion formed by interaction of a neutral molecule with a proton, and represented by the symbolism [M + H]+. The term 'protonated molecular ion' is not recommended as it suggests a different species formed by the association of a proton with a molecular ion. Likewise, the ambigous terms 'quasi-molecular ion' or 'pseudo-molecular ion' should be avoided.
Considered between 2004 and 2006 but not included in the 2006 PAC submission
