CoIn regions, respectively. The dynamically weighted solvation scheme is particularly useful for molecular dynamics simulations. However, in electron transitions, the transition probability strongly depends on the character of the excitation (i.e., whether it is allowed or forbidden), so a state-specific solvation model is ultimately needed. On the other hand, using different densities for solute and solvent polarization complicates the variational minimization process, as discussed below. Additionally, this approach introduces another type of root-flipping problem when selecting the density for polarizing the solvent. Since it is not possible to formulate a physically and mathematically satisfying model in a straightforward manner, the original formulation implemented in OpenMolcas is used in this study.
