Dear Q-chem users and support,
I am studying excited states based on TD-DFT, while i successfully managed to calculated the SOC, i am not totally confident on my results, i already used the ground state geometry of the lowest lying singlet for starts and the ground state of the complex. Both cases resulted in higher vertical energies related to the selected excited states than the ones calculated before. Then i do not know which ground state geometry should is use for this study. Hope this description helps out.
Thanks in advance
