Abstract
The theories of energy transfer in the literature are concerned with the distance between the energy donor and acceptor, distributions for these distances as controlled by concentration, averaging over these distances, etc. These concerns enter the electronic factor of the transition rate. Our concern is with the nuclear factor, i.e., with the energy mismatch dependence and with the temperature dependence of these rates. We shall see in Chap. 8 that insofar as the previous authors treat specifically these two dependences they have come to approximate forms of the W p , W p, d/dz , or M p, d/dz rates. In these treatments, and in ours also, the energy donor and the energy acceptor are treated as having vibrational modes totally independent of each other.
