The bridge length dependence of the classical transfer rate from donor to acceptor is studied for symmetric bridged systems. The reaction rate is shown to be factorizable into an escape rate from the donor well and a transmission factor through the bridge. As expected for a diffusing particle this transmission factor is inversely proportional to the bridge length, for long bridges. The Pollak‐Grabert‐Hänggi turnover theory is shown to be applicable for all friction strengths and bridge lengths studied in this paper.
