Formation of multiply charged ions is shown to contribute a significant fraction of the total ionization by high energy electrons, and multiple ionization is almost always followed by charge‐separation reactions. Triple ionization and subsequent dissociations can be well characterized by the electron‐three ion coincidence technique. Results obtained using this new technique are compared with computer simulations of the dissociations of OCS 3+ and SO 3+ 2 , and the initial momenta and relátive angles of all three fragments are thereby determined. Triply charged benzene ions are shown to undergo many competing charge‐separation reactions.
