Now I am trying to analyzing the NTO of excited states.
But I am confused in choosing the input files on multiwfn program.
To get the information of T1 NTO, I choose the TD-DFT calculation results file of T1 states.
The next step is my problem.
If I want to get the T2, T3, ... Tn (n>1) NTO, which calculation results file is correct?
I am not sure the same calculation file (T1 calculation file) is correct or the n-th excited state calculation result file itself is correct.
Please let me know the correct way.
Thank you in advance
