In this work we present a study of the dissociative photoionization of carbonylsulfenyl derivatives, XC(O)SY (X, Y: F, Cl, CH3), by using multicoincidence time-of-flight mass spectrometry and synchrotron radiation in the S 2p, C 1s, Cl 2p, O 1s and F 1s edges. Total and partial ion yield spectra together with PEPICO and PEPIPICO spectra were measured. From the many species formed during the synchrotron experiments reported in the present work at least two call our attention, HCS+ and H3+
