I'm sorry if I update this old post, however, since the question remained unsolved and since i am interested in sos expressions like < e | mu | e' >, e and e' being excited states, I'll ask that question again: is there a way (TM510 or TM6.0) to get transition dipole moments between two excited states at DFT or CC2 level ?
Thank you all in advance.
