Quantum mechanical models for the charge transfer in donor–acceptor complexes in the diabatic approximation suggest electronic transfer rates which are dependent on the energy difference between initial and final state as well as some reorganisation energy in both directions of the electron transfer, i.e., independent of the sign of the energy difference. This contrasts a ubiquitous factor 1 for jumps downward in energy and gives rise to what we believe is a more accurate description of the dynamic properties of charge transport. In order to clarify the influence of such a modification on the macroscopic charge transport, we set up dynamic MC calculations. The temperature and field dependence of the mobility for both jump rate expressions are compared. We study the effect of spatial and energetic Gaussian disorder and discuss implications for the interpretation of experimental data.
