ქიმიის ტერმინთა განმარტებითი ლექსიკონი

Coefficient of the second order term in the relation between the electric dipole moment l of a molecule
and the electric field E which acts on the molecule, µ = µ₀ + αE + βE² + γE³ . µ₀ is the permanent dipole
moment, α is the polarizability and γ is the second hyperpolarizability.

Note 1: Hyperpolarizability is a scalar for isotropic entities and a 3 x 3 tensor for others.

Note 2: SI unit: C³ m³ J^-2 .
