Dexter excitation transfer

  "id": "MLC-T-CHM-003114",
  "term": "Dexter excitation transfer",
  "field": "Chemistry",
  "definition": "A mechanism of electronic excitation energy transfer between a donor and an acceptor molecule that requires direct orbital overlap between the two species. This short-range process involves a simultaneous exchange of electrons between the donor and acceptor. The rate of Dexter transfer decreases exponentially with increasing donor-acceptor distance, typically effective within 10 Å.",
