Third-order Properties

The following third-order properties can be computed currently:

a) at the HF-SCF level it is possible to compute the static hyperpolarizability as well as Raman intensities (via geometrical derivatives of the polarizability tensor);

b) at electron-correlated level (CCSD), it is possible to compute currently static and dynamical hyperpolarizabilities, Raman intensities and Verdet constants provided the orbital relaxation effects are discarded for the electric-field (and, if applicable, magnetic-field) perturbations.
