Charge-transfer absorption

{
  "id": "MLC-T-CHM-001914",
  "term": "Charge-transfer absorption",
  "field": "Chemistry",
  "definition": "The absorption of electromagnetic radiation that results in the excitation of an electron from a donor orbital to an acceptor orbital, leading to a partial or complete transfer of charge between two molecular entities or within a single molecule. This process creates a transient excited state with a redistributed electron density. The absorption band is characteristic of the donor-acceptor interaction and often appears in the visible or ultraviolet region of the spectrum.",
