Spectroscopic studies of ionic complexes and clusters
Abstract
Ionic clusters are ubiquitous in all gas-phase environments, being particularly abundant in plasmas, flames, and the terrestrial atmosphere and are also likely constituents of the interstellar medium. Ion-induced dipole and ion-dipole forces result in bonded entities whose dissociation energies lie between those of van der Waals and fully chemically bound species. They also serve as convenient systems to investigate liquid-phase structures surrounding a solvated ion. This review is primarily devoted to discussing the spectroscopic characterization of relatively weakly bound ionic complexes. It concentrates on results obtained for quite disparate chemical species including metal ions solvated by noble gas, water or inorganic molecular ligands, protonated hydrogen, ammonia and water complexes, inorganic molecular chromophores such as N[sub 2][sup +] surrounded by rare gas atoms, and aromatic rings with one or more rare gas atoms attached. The focus of this review is on spectroscopic studies that provide direct evidence to structure. The authors do not consider the considerable body of experimental and theoretical work concerned with bound-free electronic transition in ionic complexes. Generally cation complexes consisting of two like moieties, one minus an electron, have one bound and one repulsive electronic state correlating with ground-sate fragments. Although observation of transitions between these twomore »

Although observation of transitions between these two states leads to limited structural information on the ground state of the complex, it is possible to determine binding energies and the symmetry of the transition by measuring the angular and kinetic energy distributions of the fragments. 192 refs.},
