Charge-transfer reaction (in mass spectrometry)

An ion/neutral species reaction in which the total charge on the reactant ion is transferred initially to the reactant neutral species so that the reactant ion becomes a neutral entity. Some of the possible reactions of ions M2+, M+ and M- with a neutral species X are categorized in terms of the above definitions as follows:

M2+ + X → M+ + X+ (Partial charge transfer)

M+ + X → M2+ + X + e (Charge stripping)

M- + X → M+ + X + 2e (Charge stripping & charge inversion)

These are all ion/neutral species reactions and also charge permutation reactions.

Charge-transfer reaction (in mass spectrometry)

http://goldbook.iupac.org/C01005.html

An ion/neutral species reaction wherein the total charge on the reactant ion is transferred initially to the reactant neutral species so that the reactant ion becomes a neutral entity. Considering some of the possible reactions of ions M2+, M+ and M? with a neutral species X, these would be further categorized as follows:

M2+ + X → M+ + X+ (Partial charge transfer)

M+ + X → M2+ + X + e (Charge stripping)

M- + X → M+ + X + 2e (Charge stripping & charge inversion)

All are ion/neutral species reactions and also charge permutation reactions.
