Abstract

The structures of gas phase ion-molecule complexes are generally poorly experimentally characterized in spite of the fact that their energetics are well known.1,2 In fact, one is often not sure what structural species one is dealing with. A large amount of information exists from mass spectrometry as to what kinds of reactions occur, mostly in the cases of highly vibrationally excited species, and some mechanisms can be established using isotopically labeled materials. Ironically, the use of isotopic labeling is not general in those studies in which the finer details of the energetics have been determined.1,2 With regard to what is discussed here, theoretical treatment of small cluster dynamics has not proceeded very far and will certainly be an area of increased activity over the next 10 years. On the other hand, ab initio calculations are now capable of giving fairly accurate descriptions of the structures and energies of small ion systems.
