The estimation of electron affinities fromab initio 1s orbital energies

Summary It has been found that the electron affinities of alkoxy-radicals can be estimated using a correlation with the 1s orbital energy of the oxygen on the associated alkoxy-anion, EA=–0.64503 * (1s orbital energy) –351.58. The method assumes that the species of interest accepts the electron into an orbital which is localized on the oxygen.
