The purpose of this communication is to report a CI method for calculating the electronic matrix elements between the various prosthetic groups of a bacterial reaction centre (RC), relevant for estimating the electron transfer (ET) rate in the primary charge-separation step. Although we will focus on just the elements required to estimate the ET rate for the “super-exchange” model1, the underlying procedure may be used quite generally to determine the energy ordering of the various local and charge-transfer excited states of a molecular aggregate, such as a bacterial RC. It offers a theoretical framework for investigating quite diverse optical properties of the aggregate such as, for example, Stark effects.
