Few-electron molecules represent attractive systems for precision spectroscopy because their properties can be calculated with extraordinary accuracy by ab initio quantum-chemical methods. [1,2] Comparing experimental and theoretical results thus offers the opportunity to assess the limitations of ab initio calculations, ultimately and ideally at the level where their accuracy is limited by...

58. Vibronic Coupling and Photoelectron Angular Distributions: All May Not Be As It Seems

Prof. Ivan Powis (University of Nottingham)

Talk

Improved resolution and flexible polarization control are providing new opportunities to track photoelectron angular distributions over extended photon energy ranges with full vibrational resolution. Such studies provide fresh insight into both well-established vibrational coupling mechanisms and some newer phenomena. The importance of a sound understanding and knowledge of these vibronic...

27. Advances on the identification of DNA bases specific isomers via high accuracy single photon ionization and ab initio computations

Prof. Majdi Hochlaf (Université Paris-Est, Laboratoire Modélisation et Simulation Multi Echelle)

DNA/RNA bases and amino acids are building blocks of life. The spectroscopy and stability of their ionic forms are relevant to their survival rate under interstellar conditions, and to the field of radiation damage, where ionizing radiation can lead to DNA/RNA strand breaking and production of hazardous by-products through processes involving nucleobases.
Several experimental works at BESSY...

2. Photoionization and Photoelectron Spectroscopy of Biradicals

Ingo Fischer (Universität Würzburg)

Biradicals are molecules with an electronic structure that is characterized by two unpaired electrons in degenerate or near-degenerate molecular orbitals. Their chemical and physical properties differ significantly from those of closed-shell molecules due to the interactions between the energetically close-lying states that result from the degenerate molecular orbitals. Biradicals play an...
