Electron transfer dissociation (ETD)
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.
