Resumen:
The electronic transitions and the dissociative ionic photoionization mechanismsof gaseous ClC(O)SCH3 have been investigated at the VUV and soft X-ray energyregions of S 2p, Cl 2p, C 1s and O 1s core edges using tunable synchrotron radiationand time-of-flight mass spectrometry. The relative abundances of the ionic fragmentswere obtained from both PEPICO (Photoelectron Photoion Coincidence) and PEPIPICO(Photoelectron Photoion Photoion Coincidence) spectra. The presence of a moderatesite- and element-specific fragmentation effects and its implication regarding chemicalreactions were analyzed. The relation of the current results with the interstellarchemistry is also a goal of this piece of work.
