TL;DR: Real-time analysis of samples is performed by ionizing them with elliptically polarized femtosecond laser pulses and detecting the angular distributions of the photoelectrons, able to distinguish isomers, which cannot be easily distinguished by mass-spectrometry.

Condensation Effects on Electron Chiral Asymmetries in the Photoionization of Serine: From Free Molecules to Nanoparticles
TL;DR: In this paper, angle-resolved valence photoelectron spectroscopy was used to investigate structural changes at the molecular level, occurring at the onset of condensation, which can be probed by angle-resolution valence spectrograms.

Propensity rules in photoelectron circular dichroism in chiral molecules. I. Chiral hydrogen
Andres F. Ordonez,Olga Smirnova +1 more
TL;DR: In this paper, the authors introduce instances of bound chiral wave functions resulting from stationary superpositions of states in a hydrogen atom and use them to show that the chiral response in one-photon ionization of aligned molecular ensembles originates from two propensity rules.

Application of electronic circular dichroism in configurational and conformational analysis of organic compounds
TL;DR: The discussion focuses on the application of ECD, also in combination with other methods, in structural analysis of organic compounds, including host-guest complexes, and will emphasize the importance of the interplay between configurational and conformational factors.

Asymmetric autocatalysis and amplification of enantiomeric excess of a chiral molecule
TL;DR: In this paper, it was shown that autocatalysis in a chemical reaction can indeed enhance a small initial enantiomeric excess of a chiral molecule, and that the resulting chirality imbalance can become overwhelming.

Enantiomeric Excesses in Meteoritic Amino Acids
John R. Cronin,Sandra Pizzarello +1 more
TL;DR: Gas chromatographic-mass spectral analyses of the four stereoisomers of 2-amino-2,3-dimethylpentanoic acid obtained from the Murchison meteorite show that the L enantiomer occurs in excess, indicative of an asymmetric influence on organic chemical evolution before the origin of life.

Two-dimensional charged particle image inversion using a polar basis function expansion
TL;DR: The pBasex algorithm as mentioned in this paper reconstructs the original Newton sphere of expanding charged particles from its two-dimensional projection by fitting a set of basis functions with a known inverse Abel integral, adapted to the polar symmetry of the photoionization process to optimize the energy and angular resolution.
