Physical mechanisms for non-radiative energy transfer between molecules

Physical mechanisms for non-radiative energy transfer between molecules 

One way of approaching these matters is to consider a series of processes by which an electronically-excited molecule can be progressively deactivated. Four processes can be distinguished  

Intermolecular transfer of electronic energy of excited fluorophore molecules [34] 

We have already considered chemical quenching processes of various types, such as ex-cimer and exciplex formation, in which electronically-excited molecules lose their electronic energy in the course of reaction. In some instances where fluorescence from an excited donor species D is quenched by a species A which is itself a fluorophore, the emis- 

Some representative experimental results are shown in Table 6.4, which includes systems having rate constants up to the diffusion-controlled limit ko, and Table 6.5, in which some rate constants higher than ko are recorded.
