Photodetachment

  "id": "MLC-T-CHM-008844",
  "term": "Photodetachment",
  "field": "Chemistry",
  "definition": "The loss of an electron by an anion that has absorbed a photon, which leaves behind a neutral atom or molecule. The photon energy must exceed the electron affinity of that neutral species, so the threshold energy gives the electron affinity. Removing an electron from a neutral species to give a cation is called photoionization instead.",
