We used a fluorescence resonance energy transfer donor molecule to probe the multiple intermediates in the photoinduced destruction of an acceptor molecule. These intermediates are nonemitting but are still able to quench the fluorescence of the donor at a distance scale shorter than conventional fluorescence resonance energy transfer, suggesting novel biophysical applications.
