Calculation Of Third-order Properties

Computation of static electric-dipole hyperpolarizabilities is requested via

PROP=HYPERPOL.

Currently this is only available for the CCSD approximation with either orbital relaxation included (DIFF_TYPE=RELAXED) or not (DIFF_TYPE=UNRELAXED).

Frequency-dependent hyperpolarizabilities are requested via the keywords PROP=SHG, PROP=OPT_REC OR PROP=DYN_HYP; those calculations have to be carried out with orbital relaxation turned off (DIFF_TYPE=UNRELAXED).

Verdet constants can be computed using the keyword PROP=VERDET.
