International audience; To our knowledge, no individual polycyclic aromatic hydrocarbon (PAH) molecule has yet been shown to carry all the ubiquitous and closely correlated unidentified IR (UIR) bands. More generally, no IR space observatory (ISO) in

We report an experimental and theoretical study of the double-core excitation processes in some sulfurcontainging molecules in the gas phase. Absolute X-ray absorption cross-section of H2S, SO2 and SF6 have been measured in the 2400–2800 eV region.
