Multipole-bound anions of organic molecules

Abstract

Multipole-bound anions are ions which possess weakly-bound excess electrons in diffuse orbitals. They can be either produced by electron attachment in the high-pressure region of supersonic expansions, leading to intense anion intensities allowing for photoelectron spectroscopy or by electron transfer from laser-excited atoms to cold molecular species. This review emphasizes applications of multipole-bound electron binding to the determination of structures and electron affinities of weakly-bound organic complexes. Studies involving charge-exchange between polar molecules and laser-excited surfaces, zwitterions and electron binding to molecules deposited on helium droplets are briefly considered
