摘要
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.
