Ionic fragmentation following inner-shell (Pb 5p and 4f, C 1 s) excitation of Pb (CH3)4 has been studied in the vapor phase by use of synchrotron radiation and time-of-flight mass spectrometry. The C 1 s ionization is followed by KVV Auger process, and the fragmentation proceeds by way of the doubly charged parent ion. The Pb 5p or 4f ionization is followed by a cascade of Auger events, and the fragmentation proceeds by way of the triply or higher multiply charged parent ions. The fragmentation pattern changes significantly depending on the site of the core electrons excited (Pb or C).
