Examining how shape and chirality affects luminous molecules

In physics, chirality may be found in the spin of a particle, where the handedness of the object is determined by the direction in which the particle spins. Not to be confused with helicity, which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin. Although both chirality and helicity can have left-handed or right-handed properties, only in the massless case are they identical. In particular for … Web‘This has implications for product purification and enantiomer enrichments of chiral compounds, perhaps even impacting questions related to the origin of enantioselectivities in prebiotic life.’ ...

WebMay 8, 2024 · When light is circularly or elliptically polarized, its orthogonally coupled electric and magnetic fields oscillate in a left- or right-handed helix (chiral) geometry. Likewise, a light with OAM typically exhibits a helical (chiral) wavefront shape. Thus, both SAM and OAM play a role in the chirality of light. WebBy tuning optical chirality in a precisely sculpted electromagnetic field, nature may allow enhanced discrimination of chiral molecules against their mirror counterparts.
