A further reduction in the computational cost can be achieved by avoiding geometry optimization of the ensemble of snapshots altogether and instead dressing the shifted VEE/VDEs of the ensemble of solute-solvent configurations directly with an average zero-temperature (ZT) FC lineshape. This E-avgZTFC approach accounts for temperature classically in the vibrational degrees of freedom of both the chromophore and the solvent, as there is no population of the vibrational energy levels in the zero-temperature FC lineshape. The average ZTFC lineshape is generated through the same procedure as the average FTFC lineshape, with the alignment of the 0-0 transitions. The linear optical spectrum using this approach is then obtained as,
