Electron affinity
ORANGE BOOK DEFINITION IUPAC. Analytical Division. Compendium of Analytical Nomenclature (the Orange Book). Definitive Rules, 1979 (see also Orange Book 2023)
The electron affinity of a species M is defined as the minimum energy required for the process M^- → M + e where M^- and M are in their ground rotational, vibrational and electronic states and the electron has zero potential and kinetic energy.
