:Note 3: Pseudo-molecular ion and quasi-molecular ion are deprecated; a specific term such as protonated molecule, or a chemical description such as [M + H]<sup>+</sup> should be used. | |||

[[Cationized Molecule]] | {{orange| | ||
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. | |||

An ion formed by interaction of a molecule with a proton abstracted from an ion, as often occurs in [[chemical ionization]] according to the reaction: | |||
M + XH<sup>+</sup> ? MH<sup>+</sup> + X | |||
. The symbolism [M + H]+ may also be used to represent the protonated molecule. The widely used term '[[protonated molecular ion]]' to describe the MH+ ion is not recommended, since it suggests an associated product of a proton with a molecular ion. | |||
