Abstract Single photon double ionization of carbon diselenide ( $${\hbox {CSe}}_{2}$$ ) has been investigated by means multi-particle coincidence techniques. The interpretation the experimental spectra is helped post-Hartree-Fock computations at Coupled Clusters and Multi-Reference Configuration-Interaction levels to determine energetics electronic state potentials $$\hbox {CSe}_2^{2+}$$ its fragments. lowest energy found be 24.68 ± 0.20 eV, reflecting { X} ^3\Sigma ^-_g$$ ground state, in...
<title>Abstract</title> We have measured the core-valence double ionization spectra of carbon suboxide above both O 1s and C edges. The are compared with well-known single valence photoelectron spectrum this system, from which they differ quite strongly. Auger decay following hole formation at chemically distinct central outer atoms shows strong selectivity in final multiply charged states produced. Assignment spectral features is made by comparing calculations sudden approximation assuming...
Aromatic compounds, with their stable cyclic structure and [4n+2]&#960; electrons, are resistant to chemical attack degradation. This stability makes them prevalent in celestial bodies valuable designing polymers that withstand harsh space conditions [1-4].In interstellar space, aromatic molecules make up ~20% of atomic carbon key forming complex organic [1]. Cyanopyrene, cyanonaphthalene, indene have been identified the TMC-1 molecular cloud [5]. also found Solar System objects,...
Double ionization spectra of isothiocyanic acid (HNCS) have been measured using multi-electron and multi-ion coincidence techniques combined with high-level theoretical calculations. The adiabatic double energy HNCS is found at 27.1 ± 0.1 eV associated the formation X 3A″ ground state HNCS2+. characteristics different dissociation channels are examined compared to results electronic structure calculations obtained by systematically elongating three bonds H-NCS, HN-CS, HNC-S. For instance,...
Abstract This paper reports on the characterization of stereo-dynamic controlling three different chemi-ionization reactions, recent objective our study, since they participate to balance phenomena occurring in plasma, interstellar medium, planetary atmospheres, flames and lasers. The optical potential, obtained by a phenomenological method defined whole space relative configurations reagents, has been formulated an accurate internally consistent way for systems. Some cuts multidimensional...
Total and partial ionization cross sections for Ne*(3P2,0)-HX (X = Cl, Br) are presented in a comparative way as function of the collision energy between 0.02-0.5 eV. New mass spectrometric data on Ne*-HBr chemi-ionization discussed analyzed with already published Ne*-HCl, highlighting similarities differences collisional stereodynamics two systems. Basic features interaction potentials, driving reactive collisions, suggest that reaction channels, leading to formation parent HX+ ions ground...
The article illustrates the synergy between theoretical/computational advances and advanced experimental achievements to pursue green chemistry circular economy technological implementations. specific focus concerns production of carbon neutral fuels by converting waste dioxide into methane. Both theoretical-computational means were adopted design a functional option implementing heterogeneous catalysis process (Paul Sabatier (PS) catalytic reduction) convert methane, further drive its...
<title>Abstract</title> When a molecule loses two electrons, Coulomb repulsion makes the resulting doubly charged system likely to fragment into singly ions. These monocations can be detected in correlated fashion using multiplex time-of-flight spectroscopy. The island shapes ion-ion coincidence maps derived from such two-body dissociations contain detailed information on physical processes underlying fragmentation. Here, simple method is presented where fit function used determine...

The behavior of nitrosyl chloride (ClNO) exposed to ionizing radiation was studied by direct probing valence-shell electrons in temporal coincidence with ions originating from the fragmentation process transient ClNO2+. Such a molecular dication produced double photoionization synchrotron 24-70 eV photon energy range. experiment has been conducted at Elettra Synchrotron Facility Basovizza (Trieste, Italy) using light beam linearly polarized direction polarization vector parallel ClNO axis....
