Linear and nonlinear electric properties of spatially confined LiH molecule, studied with the finite field method

The influence of spatial confinement on the electric properties: dipole moment (μ), dipole polarizability (α), first hyperpolarizability (β) and second hyperpolarizability (γ) of the LiH molecule was studied. The confining model potential is assumed in the form of a penetrable spherical box. The properties in question were calculated within the finite field approach, with an accurate, explicitly correlated wave function. We found all studied properties diminished under confinement.
