ORANGE BOOK DEFINITION

IUPAC. Analytical Division. Compendium of Analytical Nomenclature (the Orange Book). Definitive Rules, 1979.

Electron affinity

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.
