Abstract
Anions present a tempting target for theoretical study because their examination by experimental means is not straightforward. The experimental difficulties arise because isolated anions are extremely fragile. Electron affinities are normally less than a few electron volts and, hence, the extra electron is only loosely bound. It is therefore difficult to study many anionic species by conventional procedures. However, recently developed techniques such as matrix isolation(1) (for structural information) and ion cyclotron resonance(2) (for energetic information) provide promising new sources of experimental data.
