Hyperpolarizability - Wikipedia
网页The hyperpolarizability, a nonlinear-optical property of a molecule, is the second order electric susceptibility per unit volume. [1] The hyperpolarizability can be calculated using quantum chemical calculations developed in several software packages.
Hyperpolarizability - an overview | ScienceDirect Topics
网页Hyperpolarizability refers to a nonlinear response of a material to an applied electric field, where the dipole moment is proportional to the second and higher powers of the field intensity. This property leads to phenomena such as second and third harmonic generation in optoelectronic materials.

Polarizability and hyperpolarizability | Philosophical …
网页Abstract. The oscillating charge and current distributions induced in matter by a beam of light are expressed in terms of molecular polarizabilities and hyperpolarizabilities. The symmetry of these property tensors under space and time reversal is examined and methods for their measurement considered.
