Charge-transfer complex

{
  "id": "MLC-T-CHM-001916",
  "term": "Charge-transfer complex",
  "field": "Chemistry",
  "definition": "An adduct formed between two or more molecular entities, one acting as an electron donor and the other as an electron acceptor, where a fraction of electronic charge is transferred from the donor to the acceptor. This interaction is weaker than a covalent bond but stronger than typical van der Waals forces. These complexes often exhibit characteristic absorption bands in the visible or ultraviolet region, distinct from those of the individual components.",
