A doubt about dipole moment of water molecule quantum. For the ground state this would be scf and ci includes cisingles, tddft and other ci methods. For example, if you want to make gaussian output dipole moment for the 4th. If 5050 is requested, nstates gives the number of each type of state for which to solve i. Ground state dipole moment is outputted by default, you can find it by carefully.

The gaussian output does not print the dipole strengths, d i, but instead reports the oscillator strengths. Rutheniumii complexes are widely used as photosensitisers for electron transfer, but given their high intrinsic symmetry, the origin of the excited state dipole moment is unclear.
