  "id": "MLC-T-CHM-009842",
  "term": "Radiative de-excitation",
  "field": "Chemistry",
  "definition": "The process by which an excited atom, molecule, or nucleus returns to a lower energy state by emitting a photon. This occurs when the internal energy of the excited species is converted into electromagnetic radiation. The emitted photon's energy corresponds to the energy difference between the initial and final states.",
