(11) Figure illustrates the relationship between these parameters and an FDTD-derived absorption spectrum. Also provided is the spectrum generated according to the solution of the equation of motion for the donor, in the absence of the acceptor, using the parameterized model Hamiltonian. The model Hamiltonian yields a spectrum that is in reasonable agreement with that from the electrodynamics simulations, and we note that the absorption features can be attributed to the metal components of the CNP, as the dielectric is lossless in this energy window. Details of the electrodynamics simulations and the treatment of the CNPs within these simulations can be found in the Supporting Information (SI).
