Calculation Of Frequency-dependent Hyperpolarizabilities

Computation of dynamical electric-dipole first hyperpolarizabilities is requested via the following keywords

For the general hyperpolarizability (-wy-wz;wy,wz)

PROP=DYN_HYP

For a second-harmonic-generation (SHG) hyperpolarizability (-2w;w,w)

PROP=SHG

For an optical-rectification (OR) hyperpolarizability (0;w,-w)

PROP=OPT_REC

An additional %frequency section is required in the ZMAT file, which should contain for a general hyperpolarizability two frequencies and for SHG and OR hyperpolarizablities a single frequency.

Currently this is only available for CCSD and with no orbital relaxation (DIFF_TYPE=UNRELAXED) and is not available for ABCDTYPE=AOBASIS.

Examples

SHG calculations
OR calculations
general hyperpolarizability calculations
