Fragmentation of CF{sub 3}Br induced by fluroine is core excitation: Energy resolved auger electron multiple-ion coincidence measurements
- and others
Fragmentation processes in CF{sub 3}Br near the F K edge were investigated using synchrotron radiation and Energy Resolved Auger Electron Multiple Ion Coincidence (ERAEMICO). Time-of flight mass spectra were collected in coincidence with either selected F 1s Auger or resonant-Auger electrons which were energy analyzed with a hemispherical detector. In addition, a more inclusive mass spectrum was taken near the F 1s ionization potential in coincidence with low energy electrons. Preliminary spectra the Br{sup 2+} ion intensity is negligible and the relative CF{sup +} abundance is higher. These differences confirm the notion that the electronic state prior to bond breakage governs the resulting fragmentation pattern.
