We present here for the rst time the Total Ion Yield (TIY) spectra of CH3C(O)SCH3, in the 12-300 eV range (available at the TGM facility of the LNLS). This energy range allows us to record the S 2p and C 1s edges. TheC 1s and S 2p ionisation energies have been extracted from the TIY spectra and compared with those calculated based on the equivalent-core approximation taking OCS as a reference compound. The analysis of the PEPICO spectra reveals interesting aspects related with the possibility of site-speci c fragmentation.
