Descripción
Total ion yield spectra and photoinduced fragmentations following S 2p, C 1s, O 1s, and F 1s inner shell excitations of methyl thiofluoroformate, FC(O)SCH3, have been studied in the gaseous phase by using synchrotron radiation and multicoincidence techniques, which include photoelectron−photoion coincidence (PEPICO) and photoelectron−photoion−photoion coincidence (PEPIPICO) time-of-flight mass spectrometry. Fragmentation patterns deduced from PEPICO spectra at the various excitation energies show a moderate site-specific fragmentation. The dissociation dynamic for the main ion-pair production has been discussed. Two-, three-, and four-body dissociation channels have been observed in the PEPIPICO spectra, and the dissociation mechanisms were proposed. The high stability of the interstellar HCS+ ion can be observed over the whole range of photon energies analyzed.
