The Coulomb-coupling in terms of transition density partial charges $\{q^T\}$ can be thought of as the interaction of  \begin{equation}  J_{AB}^{ij} = \sum_{a\in A} q_{a,i}^T \phi_a^T (B_j)  \end{equation}  where the \emph{direct} potential from the $j$'th excited state of chromophore $B$ onto the atomic sites $a$ in chromophore $A$ is  \begin{equation}  \phi_a^T (B_j) = \sum_{b\in B} \frac{q^T_{b,j}}{|\mathbf{R}_a - \mathbf{R}_b|}  \end{equation}.
