Popis: Some bis-benzyltetrahydroisoquinolines [α,α′-di-N,N-(1-benzyl-1,2,3,4-tetrahydroisoquinoline)-p-xylene and various substituted analogues] give rise to very abundant doubly charged fragment ions under electron impact, corresponding to the loss of the two benzyl groups. Substituent effects, ionization and appearance energy measurements and metastable transitions show that these doubly charged ions are formed (at least in part) from singly charged precursors by a heterolytic cleavage (charge separation).
