The implicit solvent FTFC spectral lineshapes, shown in Figure , display asymmetry from the vibronic tail and show relatively good agreement with the experimental lineshape (FWHM values of 0.330 and 0.381 eV for absorption and emission, respectively), with both absorption and fluorescence being slightly underestimated in width by 0.011 eV and 0.019 eV, respectively. The computed Stokes shift determined from the lineshape spectral maxima is 0.123 eV, thus significantly underestimated compared to the experimental value of 0.334 eV (see Table ). Overall, the implicit solvent model predicts toonarrow spectral lineshapes and underestimates the Stokes shift when we employ the default broadening factor of 135 cm -1 .
