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.
气态 ClC(O)SCH(3) 的电子跃迁和离子光解机制已在 S 2p、Cl 2p、C 1s 和 O 1s 芯边的 VUV 和软 X 射线能区，使用可调谐同步辐射和飞行时间质谱进行了研究。离子碎片的相对丰度是从 PEPICO（光电子光离子符合）和 PEPIPICO（光电子光离子光离子符合）谱中获得的。分析了存在适度的位和元素特异性碎裂效应及其对化学反应的影响。目前的结果与星际化学的关系也是这项工作的目标之一。
