  "id": "MLC-T-CHM-003759",
  "term": "Electronically excited state",
  "field": "Chemistry",
  "definition": "An electronic state of an atom or molecule that possesses higher energy than its ground state. This occurs when an electron transitions from a lower energy orbital to a higher energy orbital, typically through the absorption of a photon or by thermal excitation. The lifetime of an excited state can range from femtoseconds to several seconds.",
