摘要: Abstract Internal conversion is the dominant relaxation channel from higher lying excited states in molecular crystals and involves transfer of energy electronic system to lattice. In this work, we present results simulations nonradiative process with an emphasis on both intra- interband transitions. We find internal be strongly nonadiabatic associated time case large excitations limited by transitions made between different bands.
