    "abstract": "Based on the reduced density matrix method, we compare two different\napproaches to calculate the dynamics of the electron transfer in systems with\ndonor, bridge, and acceptor. In the first approach a vibrational substructure\nis taken into account for each electronic state and the corresponding states\nare displaced along a common reaction coordinate. In the second approach it is\nassumed that vibrational relaxation is much faster than the electron transfer\nand therefore the states are modeled by electronic levels only. In both\napproaches the system is coupled to a bath of harmonic oscillators but the way\nof relaxation is quite different. The theory is applied to the electron\ntransfer in ${\\rm H_2P}-{\\rm ZnP}-{\\rm Q}$ with free-base porphyrin (${\\rm\nH_2P}$) being the donor, zinc porphyrin (${\\rm ZnP}$) being the bridge and\nquinone (${\\rm Q}$) the acceptor. The parameters are chosen as similar as\npossible for both approaches and the quality of the agreement is discussed.",
