The unique role that electric quadrupole transition moments can play in chiroptical interactions has recently been established with twisted light beams. Manifesting a spin-orbit interaction in paraxial light, the engagement of electric quadrupoles in electronic transitions is highlighted in optical phenomena such as absorption, in both chiral and achiral media. However, spin-orbit interactions of light are also well-known in scattering from small particles, and recent exploratory experimental work suggests a chiroptical interaction of this nature in the scattering of optical vortex beams. Using a quantum electrodynamical formulation, such a sensitivity to the handedness of a vortex beam is accounted for in molecular scattering processes.
