摘要：

Simple dispersion relations are derived which allow for the separation of the contributions of direct electron transfer and hole transfer to the total matrix element between donor and acceptor states in donor-bridge-acceptor charge transfer systems. The proposed relations are based on the calculation of the total matrix element for complex tunneling energies and do not assume diagonalization of the bridge orbitals. A numerical procedure to perform such calculations for proteins and other large electron transfer systems is described.
