The electronic transitions and the dissociativeionic photoionization mechanisms of gaseous ClC(O)SCH3have been investigated at the VUV and soft X-ray energyregions of S 2p, Cl 2p, C 1s, and O 1s core edges using tunablesynchrotron radiation and time-of-flight mass spectrometry.The relative abundances of the ionic fragments were obtainedfrom both PEPICO (photoelectron photoion coincidence)and PEPIPICO (photoelectron photoion photoion coincidence)spectra. The presence of a moderate site- and element-specific fragmentation effects and its implication regardingchemical reactions were analyzed. The relationship of the current results with the interstellar chemistry is also a goal of this pieceof work.
