Abstract: | The electronic transitions and the dissociative ionic photoionization mechanisms of gaseous ClC(O)SCH(3) have been investigated at the VUV and soft X-ray energy regions of S 2p, Cl 2p, C 1s, and O 1s core edges using tunable synchrotron radiation and time-of-flight mass spectrometry. The relative abundances of the ionic fragments were obtained from 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 regarding chemical reactions were analyzed. The relationship of the current results with the interstellar chemistry is also a goal of this piece of work. |
