Calculated Electron Affinities

Caution! Results of electron affinity calculations are very dependent on the basis set. Many species have anions that are not bound with respect to a free electron and the neutral species, in which case the calculations may give results that are not meaningful. By convention a positive electron affinity indicates a bound species.
