We also depict in the middle row of Figure the aver-age ZTFC and FTFC lineshapes from ten randomly chosen snapshots generated from energetically aligned individual vibronic FC spectra. The optimized VEEs/VDEs and unoptimized VEEs/VDEs, shifted 90 using the average 0-0 transition values from the same snapshots that generate the average FC lineshape, are combined with the average FTFC and ZTFC lineshapes and then summed to produce the E opt -avg 10 FTFC and E-avg 10 ZTFC spectra, respectively, shown in the bottom row of Figure .
