TL;DR: This work presents a newly developed aerosol mass thermodesorption setup, which has been coupled to a Velocity Map Imaging (VMI) analyzer operated in coincidence with a Wiley-McLaren Time of Flight spectrometer, using synchrotron radiation as a single photon ionization source.

TL;DR: The analytical potential of the so-called PECD-PICO detection technique-where the electron spectroscopy and circular dichroism can be obtained as a function of mass and ion translational energy-is underlined and applied to characterize the origin of the various species found in the experimental mass spectra.

TL;DR: In this article, photoelectron circular dichroism was used to reveal a strong overall asymmetry for the outermost orbital of alanine, which is independent of sample temperature and conformer population.

TL;DR: The imaging technique applied on the photoelectron signal allows a slow photoelectrons spectrum with a 40 meV resolution to be extracted, indicating that photoionization around the adiabatic ionization threshold involves a complex vibrational overlap between the neutral and cationic ground states, as was previously observed in the literature.

TL;DR: The results of quantum chemical calculations of the cation electronic state geometries, vibrational frequencies and energies, as well as of the C-H dissociation potential energy profiles of the ground and electronic excited states of the ion are compared with experimental observations.
