Energy transfer (ET) is greatly enhanced in a very short time after the initialelectronic state was prepared by photon excitation. ET is assisted by violentlattice vibrations which have not been relaxed yet, wzhen electrons interact stronglywith phonons in the two electronic states (coupled by the matrix element J). Anexpression of the quantum yield of ET, which bridges the nonadiabatic (small J)and the adiabatic (large J) limits, is given as a function of time elapsed afterpulsed excitation at an energy E'. In the case of steady excitation, transitions duringvibrational relaxation manifest themselves in a stron: E detcendence of the ctuan-tum yield. Generalization of F6rster's formula for ET in this dynamic regime isalso mentioned. We use a formulation developed in the part I (J. Phys. Soc.Jpn. 49 (1980) 1701) which treat transitions after vibrational relaxation. TheLandau-Zener formula plays an important role in describing ET.
