A donor-acceptor molecule, N,N-dimethylaminobenzonitrile, was used to test the validity of our COMSOL simulations, dipolar relaxation time calculations, and overall analysis. DMABN has been extensively studied because of it's intramolecular charge-transfer (ICT) excited-state and resulting dual-emission; in particular, John Warman has reported on its kinetics, ground-state dipole moment and excited-state dipole moments using dielectric-loss spectroscopy, making it an ideal reference compound for our work. DMABN has two singlet states in equilibrium, a locally excited-state (LE) and the intramolecular charge transfer state (ICT). The LE state has a dipole moment that is only slightly larger than that in the ground-state at 9.7 D; whereas, the ICT state's dipole moment is significantly larger than the ground-state at 15.1 D. The initial LE-ICT singlet state relaxes through a triplet state that has a dipole moment approximately equal to that of the LE state, with its inter-system crossing yield being correlated to the solvent's polarity. The CT state is stabilized by the solvent's polarity as well, thus the ratio of CT:LE is higher in polar solvents and the CT state's dipole moment dominates the TRDL signal at early times when the singlet state is evolving.
