Definitions of electron and energy transfer processes
In both electron transfer and energy transfer we define
a donor and an acceptor. In electron transfer there are
three types of processes. The general theory applies to
all three, but they are different in the details.
Charge separation DA ® D+A-
Charge recombination D+A- ® DA
In energy transfer there is the transfer of excitation
energy from one molecule to another.
Excitation transfer D*A ® DA*
