Förster excitation transfer

  "id": "MLC-T-CHM-004602",
  "term": "Förster excitation transfer",
  "field": "Chemistry",
  "definition": "A non-radiative energy transfer mechanism between an excited donor molecule and an acceptor molecule, occurring via long-range dipole-dipole coupling. This process is highly dependent on the spectral overlap between the donor's emission and the acceptor's absorption, as well as the distance and relative orientation of the molecules. The efficiency of transfer decreases with the sixth power of the distance between donor and acceptor.",
