We note that the exciton coupling model is straightforward to apply to multi-chromophore systems since only one molecule is treated with QM at any one time thus keeping the computational costs down. As such, the exciton coupling model can be used to treat solutesolvent systems where the solvent molecules might become part of the exciton simply by treating some of the solvent molecules as chromophores and thus contributing to the explicit description of the delocalized excitation. This exciton procedure is compared to calculations where the same solvent molecules have been included directly in the QM part of the system.
