title: Bond-forming reactions of small triply charged cations with neutral molecules.
abstract: Time-of-flight mass spectrometry reveals that atomic and small molecular triply charged cations exhibit extensive bond-forming chemistry, following gas-phase collisions with neutral molecules. These experiments show that at collision energies of a few eV, I(3+) reacts with a variety of small molecules to generate molecular monocations and molecular dications containing iodine. Xe(3+) and CS2(3+) react in a similar manner to I(3+), undergoing bond-forming reactions with neutrals. A simple model, involving relative product energetics and electrostatic interaction potentials, is used to account for the observed reactivity.
