Charge-transfer reaction (in mass spectrometry)

DRAFT DEFINITION
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.
Considered between 2004 and 2006 but not included in the 2006 PAC submission

Orange Book Entry

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 M^2+, 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.
