TICT state

{
  "id": "MLC-T-CHM-012056",
  "term": "TICT state",
  "field": "Chemistry",
  "definition": "A twisted intramolecular charge transfer state, formed when a molecule undergoes a substantial change in its geometry upon excitation, leading to a separation of charge. This state often involves a large dihedral angle between donor and acceptor moieties within the same molecule. TICT states are characterized by a large Stokes shift in their fluorescence emission compared to the locally excited state.",
