| Molecular fragmentation following photon excitation of core electrons from K shells of C and O and L shell of S atoms forming the OCS molecule was studied. Emerging photoelectrons and charged fragments were detected in coincidence. Application of time-of-flight spectroscopy together with triple coincidence photoelectron-photoion-photoion, double coincidence photo-electron-photoion and photoion-photoion techniques allow a detailed insight into the geometry and the dynamics of the de-excitation processes and an unambiguous assessment of all fragmentation channels of highly excited molecules. Such studies are of major interest in fundamental research and they are relevant also in environmental, biological and technological investigations. |
