“…non-vanishing zero-frequency components of the expected value of the electric dipole operator) normal to the polarization plane and with opposite directions for opposite enantiomers. Indeed, such static electric dipoles have been investigated in the context of optical rectification [24][25][26][27][28], where two excited states close in energy are resonantly excited with monochromatic circularly polarized light. Very recently enantiosensitive static dipoles have also been studied in the context of molecular orientation induced by intense off-resonant light pulses [29][30][31][32].…”

We find that two-color fields can induce field-free permanent dipoles in initially isotropic samples of chiral molecules via resonant electronic excitation in a one-$$3\omega $$ 3 ω -photon versus three-$$\omega $$ ω -photons scheme. These permanent dipoles are enantiosensitive and can be controlled via the relative phase between the two colors. When the two colors are linearly polarized perpendicular to each other, the interference between the two pathways induces excitation sensitive to the molecular handedness and orientation, leading to uniaxial orientation of the excited molecules and to an enantio-sensitive permanent dipole perpendicular to the polarization plane. We also find that although a corresponding one-$$2\omega $$ 2 ω -photon versus two-$$\omega $$ ω -photons scheme cannot produce enantiosensitive permanent dipoles, it can produce enantiosensitive permanent quadrupoles that are also controllable through the two-color relative phase.

“…Earlier, we showed that pre-resonant optical rectification via the second-order electric dipole mechanism [15,16,18,19] can appear in an isotropic medium composed of chiral molecules and can be induced only by an optical wave which has to be circularly (η 0 = π/4) or elliptically polarized (η 0 = 0) at incidence on the medium. The use of a linearly polarized or unpolarized (η 0 = 0) pre-resonant optical wave reduces the space function F (d) and…”

“…Non-resonant optical rectification is electric-dipole-allowed in optically active liquids and solutions only via the fourth-order electric susceptibility, arising from the nonlinear electric dipole interaction of chiral molecules with the electromagnetic field [17]. However, in absorption bands of optically active molecular systems, optical rectification is also allowed via the imaginary part of the second-order electric susceptibility [15,16,18,19].…”
