charge-transfer reaction

in mass spectrometry

https://doi.org/10.1351/goldbook.C01005

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:

C01005-2.png

C01005-3.png

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