The E opt -avg 10 FTFC and E-avg 10 ZTFC spectra are shown in Fig. . In contrast to the NBD results, for NR, the E-sum 100 FTFC and E opt -avg 10 FTFC fluorescence spectra agree in width and shape with the experiment, whereas the absorption spectrum is predicted to be too narrow by both methods. For the E-avg 10 ZTFC method, the lineshapes remain a bit jagged, and there is an increase in lineshape width, leading to an overly broad fluorescence lineshape. We also see for fluorescence that there are clearly a few high-energy outlier VDEs that lead to an unphysical high-energy fluorescence spectral onset. The Stokes shift predicted by all three methods, see Table , remains underestimated compared to the experiment. Overall, the more affordable E optavg 10 FTFC method is again in good agreement with the E-sum 100 FTFC method, with the E-avg 10 ZTFC showing more of a discrepancy with some unphysical jaggedness remaining in the spectrum.
