| 摘 要： | 本文利用飞秒时间分辨的质谱技术，研究了二氯亚砜分子在235 nm泵浦下的超快光解过程.实验记录了母体离子产率随泵浦-探测延迟时间的变化趋势，测得235 nm泵浦下的初始激发态寿命为166 fs.需要注意的是，实验中不仅观察到了二氯亚砜分子逐步解离过程还观察到了协同解离过程.

| Abstract: | The ultrafast photodissociation dynamics of thionyl chloride after excitation with a 235 nm pump pulse has been studied using a femtosecond time-resolved mass spectroscopy. The observed parent transient suggests that the excited states initiated by 235 nm are very shortlived, that is, approximately 166 fs. Not only a stepwise three-body dissociation pathway but also a concerted three-body dissociation pathway is observed. |
