Ionic fragmentation following the photoionization of Sn(CH3)4 has been studied over the energy range of 60-260 eV using synchrotron radiation and time-of-flight mass spectrometry. The Sn:4d photoionization above 60 eV is presumed to produce predominantly a doubly charged ion which dissociates into two singly charged ions and some neutral fragments. The ions predominantly produced in this pathway are CH3+, C2H3+, C2H5+, SnCHm+ and/or Sn+. The Sn:4p photoionization possibly produces a triply charged parent ion and enhances the production of H+, CHm′+ (m′=0-3) and Sn+ significantly.
