Empirical potential function calculations were carried out in order to investigate, in detail, the molecular structural characteristics of the C 2 ‐symmetric chlorophyll special‐pair dimer proposed by Boxer and Closs and Shipman et al. as a model of P700, the phototrap pigment in photosystem 1 of plants. The results indicate that the calculated minimum energy structure corresponds to a stable minimum and is closely related to the proposed special‐pair dimer structure.
