We have studied site-specific fragmentation caused by F 1s photoionization of free CF3SF5 molecules. Energy-resolved electrons and mass-resolved ions were detected in coincidence. We found an enhancement of the CF3+ ion production in coincidence with photoelectrons emitted from F atoms in the SF5 group due to a reaction path leading to CF+-SF+ pair production. We found an enhancement of the CF+ and C+ ions due to F Is electron emission from the CF3 group. Site-selectivity was also observed for the CF+-SF+, CF+-SF+, CF+-SF+, C+-F+, C+-S+ and C+-SF+ ion pair production (c) 2006 Elsevier B.V. All rights reserved.
