Non-vertical energy transfer

{
  "id": "MLC-T-CHM-008061",
  "term": "Non-vertical energy transfer",
  "field": "Chemistry",
  "definition": "An energy transfer process with a small Franck-Condon factor, because the donor or the acceptor has an excited-state equilibrium geometry strongly displaced from its ground-state geometry. The transfer therefore requires nuclear rearrangement and is slower than vertical transfer, in which both partners keep nearly the same geometry in the two states.",
