    #1 Multiwfn and wavefunction analysis The way to analyze the NTO of n-th excited states 2020-07-09 16:35:40

    Hello all.

    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

    Thank you, sir.

    It was so helpful for me.

    I have an additional question.
    I understood the way to calculate the vertical transition energies.
    My question is that

    Which function should I use to analyze the energy difference between ground and excited state in an adiabatic way?
    I mean the way to compare the two energy states in the multiwfn program.

    Thank you for your kindness.

    Hello.

    First of all, I want to thank you for making a great program. It was very helpful in my research works.
    I am really appreciative of you, sir.

    Now, I am trying to analyze some excited states of organic materials.
    I wonder whether the multiwfn program can show excited state energies or not.
    I would like to calculate some excited energies of singlets and triplets.
    My questions are that

    1. How can I get the vertical transition energy from the ground state to excited states (S1, T1, ...)?
    2. How can I get the adiabatic transition energy from the ground state to excited states?


    I will wait for your reply.
    Thank you.
