Hello,
I am sorry to update such an old topic, but I would like to ask again since my case is related. Back in 2009 there was an answer about this, but now I am working with a heavy molecule (ZnTPP, ~77 atoms), so I need to clarify.
Because of the system size, I would like to use the DFT level to calculate transition moments between excited states more efficiently. I once tried with CC2, but it took more than a month and I had to abort the calculation.
So I have two questions:
1. With Turbomole 7.9, is it possible to calculate transition moments between excited states at the DFT level?
2. Is it normal that a CC2 calculation for a system like ZnTPP would take more than one month, or does this indicate I might be doing something wrong?
Thank you very much for your time and advice.
Best regards,
Hyunjong
