In the case of Formylchloride, the scaling parameter had to be adjusted to avoid dissociation when optimizing the first excited singlet state. Further studies are required to investigate the optimal fraction of exact exchange for periodic systems since the choice might differ from the values that were originally suggested for molecular systems. Further empirical shifts might also be required when combining the sTDA excited-state method with corresponding semiempirical ground-state calculations. A consistent setup which remains to be investigated but which we expect to pave the way to treat even larger systems. It also remains to be investigated in future work if efficiency and accuracy of ADMM-approximated hybrid functional TDDFT and sTDA are beneficial for excited-state molecular dynamic simulations.
