Propensity rules for photoelectron circular dichroism in strong field ionization of chiral molecules

Abstract

Chiral molecules ionized by circularly polarized fields produce a photoelectron current orthogonal to the polarization plane. This current has opposite directions for opposite enantiomers and provides an extremely sensitive probe...

Molecular Chirality and Its Monitoring by Ultrafast X-ray Pulses

“…Ultrafast measurements of PECD are also being developed using sources from the IR to the EUV regimes . The asymmetry in tr-PECD can originate from the nuclear chiral geometry and from electronic chiral currents . tr-PECD has recently been measured on photoexcited fenchone at the C K-edge at FERMI .…”

Ultrafast chirality: the road to efficient chiral measurements

“…These chiral atoms can also display PECD upon ionization with a circularly polarized field. 130,131,190,192 The experimental demonstration of PECD on chiral atoms will require efficient excitation schemes. Such schemes have recently been proposed in the first theoretical works on using locally chiral light to imprint chirality on atomic ensembles, 130,131 supporting our general expectation that the non-perturbative interaction of locally chiral light with atoms will in general lead to chiral superpositions of states.…”

Trends in angle-resolved molecular photoelectron spectroscopy

“…At a more theoretical level, a deeper analysis based on the underlying symmetries has been presented in a series of papers. [287][288][289][290] This allows to predict the type of chiral signal expected from any specific arrangement of the external fields.…”
