  "id": "MLC-T-CHM-009846",
  "term": "Radiative transition",
  "field": "Chemistry",
  "definition": "A process in which an atom, molecule, or ion changes its energy state by absorbing or emitting a photon. This involves the interaction of electromagnetic radiation with matter, leading to a change in the electronic, vibrational, or rotational energy levels. Examples include fluorescence, phosphorescence, and absorption of light.",
