✦ Synopsis

Ionic fragmentation following the photoionization of Sn( CH,)I 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 CH: , C, H: , &H:, SnCHt and/or Sn +, The Sn: 4p photoionization possibly produces a triply charged parent ion and enhances the production of H+, CH$ (m' =O-3) and Sn+ significantly.
