Exploring the limits of Förster theory for energy transfer at a separation of 20 A.
Cutting the corner: An excellent agreement has been obtained between experimental and computed coulombic coupling matrix elements for donor-spacer-acceptor systems, which consist of a boron dipyrromethane donor and acceptor in various stages of protonation. This correlation occurs in spite of reservations about the validity of Förster theory being applied to intramolecular electronic energy transfer (ET) over short (e.g., 20 A) distances (see picture).
