Despite the crucial role of photoinduced electron transfer (ET) reactions in photosynthetic energy conversion, the factors that control this reactivity remain poorly understood. Recent theoretical work indicates the importance of orientation effects on the rates of the nonadiabatic ET process between diporphyrin pairs. This paper reports more comprehensive geometric effects in an extensive array of hybrid metal complexes consisting of zinc porphyrin (ZnP) and ferric porphyrin chloride (Fe{sup III}PCl). Diporphyrin models studied here include a variety of mutual orientations and different kinds of aromatic spacers such as benzene, naphthalene, and spirobiindan.
