Exchange-mediated energy transfer in viscous media

4 EXCHANGE-MEDIATED ENERGY TRANSFER IN VISCOUS MEDIA 

Values of g(z) are given by Rice and Pilling [39]. Typically, A 108 s-1 and so, for times longer than 1 ps, z 100. In this case, the leading term in eqn. (100b) is dominant, whence, to a fairly good approximation 

Inokuti and Hirayama [185] derived these expressions from a rather less formal approach by considering the ensemble-averaged rate of decay of each donor by energy transfer to each acceptor. A more detailed and general analysis has been given by Allinger and Blumen [186], Finally 

Pilling and Rice [39, 134] have shown that these static decay expressions (100) are applicable over times, tD
