The unimolecular decomposition of single ethylene ions in association with argon clusters containing more than 100 atoms has been observed. Fragmentation on these large clusters provides strong support for the proposal that a charge-transfer mechanism is responsible for exciting the molecular ions. In addition, the results show evidence of enhanced fragmentation for those moleo ular ions associated with a "magic number" of inert gas atoms. From these observations it is suggested that reactant ions lie on, or close to, the surface of a cluster.

## Abstract Gas‐phase ion–molecule reactions of transition metal ions, M^+^ (M^+^ = Ni^+^, Co^+^, Fe^+^ and Mn^+^), with six aromatic ring‐containing nitriles were investigated in a modified fast atom bombardment (FAB) source. It is shown that the monoadduct, (Ph(CH~2~)~__n__~CN)–M^+^, is one of th
A variety of closed shell hydrocarbon ions have been observed following charge transfer from Zn + to isobutylene (Call 8) in a high-pressure mass spectrometric (HPMS) source. The time profiles of these ions and their strong pressure dependence suggest that consecutive and sequential ion-molecule rea
