Site-selective ion pair production via normal Auger decay of free CH3F molecules studied by electron-ion-ion coincidence spectroscopy

Site-specific fragmentation caused by C KVV and F KVV Auger decay of free CH3F molecules has been studied by electron-ion-ion coincidence spectroscopy. Strong enhancements for the production of CH3+-F+ and H+-CF+ ion pairs were found for the F KVV and C KVV Auger decays, respectively.
