Gas Phase Measurements of Electron Affinities

Since the dipole bound anions are formed by double-photon absorption, the valence states could also be formed, in which case the onsets and initial peaks results from the photodetachment of the isolated ground-state or excited-state anions. These can be a measure of the Ea. The onsets that are lower than the
