Preferred Label : protonated molecule;
Detailed label : protonated molecule in mass spectrometry;
IUPAC definition : 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 MH X
. The symbolism [M H] sup class plus /sup may also be used to represent the protonated
molecule. The widely used term 'protonated molecular ion' to describe the MH sup class
plus /sup ion is not recommended, since it suggests an associated product of a
proton with a molecular ion.;
