We report here results concerning the S 2p, Cl 2p and O 1s ionization edges of CH3OC(O)SCl, that include the measurement of the Total Ion Yield (TIY) spectra around each ionization edge and the use of multicoincidence techniques, such as Photoelectron-Photoion-Coincidence (PEPICO) and Photoelectron-Photoion-Photoion-Coincidence (PEPIPICO) time of flight (TOF) mass spectrometry achieved by using the TGM (12-300 eV) and SGM (240-1000 eV) beamlines available at the LNLS (Campinas, Brazil) facilities. A site site-specific fragmentation behaviour is observed and two-body and three-body mechanisms dissociation channels were found.
