| Process in which multiply protonated molecules accept an electron from an anion with relatively low electron affinity. Capture of the electron leads to the liberation of energy and a reduction in charge of the ion with the production of the [M + nH](n-1)+• odd-electron ion, which is readily fragmented by collision-induced dissociation. |
