文摘
Small penta-atomic molecules like FC(O)SCl and ClC(O)SCl have been analyzed by using both photoelectronspectroscopy (PES) and results derived from the use of synchrotron radiation in the same energy range. Forthis second experiment total ion yield (TIY), photoelectron photoion coincidence (PEPICO), and partial ionyield (PIY) spectra have been recorded. This set of data together with results obtained by computationalchemistry allow us to study electronic properties and the ionization channels of both species. Thus, whereasthe photodissociation behavior of FC(O)SCl can be divided into three well-defined energy regions, thefragmentation dynamics of ClC(O)SCl seems to be more complex. Nevertheless, simultaneous evaluation ofthe PES and valence synchrotron photoionization studies helps to clarify the molecular ionization processes.
