In the Martian atmosphere, CO2 clusters are predicted to exist at high altitudes motivating a deeper understanding of their photochemistry. Here the authors use quantum chemistry calculations and multi-coincidence mass spectrometry to show that a siz

Experimental and theoretical near-edge x-ray-absorption fine-structure studies of NO+

Experimental near edge x ray absorption fine structure NEXAFS spectra of the nitrosonium NO ion are presented and theoretically analyzed. While neutral NO has an open shell, the cation is a closed shell species, which for NEXAFS leads to the simplici

Breaking inversion symmetry by protonation : experimental and theoretical NEXAFS study of the diazynium ion, N2H+

As an example of symmetry breaking in NEXAFS spectra of protonated species we present a high resolution NEXAFS spectrum of protonated dinitrogen, the diazynium ion N2H . By ab initio calculations we show that the spectrum consists of a superposition

In this paper, we examine decay and fragmentation of core-excited and core-ionized water molecules combining quantum chemical calculations and electron-energy-resolved electron–ion coincidence spectroscopy. The experimental technique allows us to c

In many cases fragmentation of molecules upon inner-shell ionization is very unspecific with respect to the initially localized ionization site.
