Transition moment between ground state and excited state: <0|A|ex>

This part has already been contained in the TD-DFT module for the transition dipole moment between the ground and excited states. Maybe in future there will be a subroutine for other kind of properties.

Properties from Quadratic Response Functions (QRF)

Ground-state Hyperpolarizabilities: 2_hyper_h2o

Two-photo absorption from single residues of QRF: 3_single_h2o

<S|r|S'> from double residues of QRF: 4_double_h2o_dpl

Phosphorescence from single residues of QRF: 5_phos_h2o

<T|r|T'> from single residues of QRF: 6_t_h2o_dpl

<T|Hso|T'> from double residues of QRF: 7_t_h2o_hso
