We have started with the study of the different processes occurring as result of the interaction between photons with energies in the range of 12-1000 eV and molecules corresponding to the sulfenylcarbonyl family of compounds XC(O)SY, such as FC(O)SCl, ClC(O)SCl, CH3C(O)SH, CH3C(O)SCH3 and CH3OC(O)SCl. The analysis of the PEPICO spectra suggests the possibility of site-specific fragmentation. A new three-body dissociation mechanism defined as Secondary Decay after an Ion Rearrange (SD-IR) was proposed in order to explain the dissociation process involving two double coincidences, namely F+/Cl+ and CO+/S+ in FC(O)SCl.
