The main limitation is that the quantum nature of the vibronic features (and related broadening) typically due to high-frequency modes of the excited molecule are not accounted for in this classical approach. To go beyond CEA-VE, a QM treatment of high-frequency modes and vibronic effects, which yet preserves a realiable description of the low frequency dynamical effects, is necessary. MQC approaches, such as the cumulant method and the Adiabatic-Molecular Dynamics Generalized Vertical Hessian Approach (Ad-MD|gVH), have been developed to address this challenge. For target molecule VII (i.e. dithiophene), we utilize the Ad-MD|gVH, which partitions the coordinates of the entire system (solute + medium) into soft and stiff modes.
