Abstract

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 CF₃⁺ s(-) SF⁺ pair production. We found an enhancement of the CF⁺ and C⁺ ions due to F 1s electron emission from the CF₃ group. Site-selectivity was also observed for the CF⁺-SF⁺, CF⁺ s(-) SF₂⁺, CF⁺ s(-) SF₃⁺, C⁺-F⁺, C⁺-S⁺ and C⁺-SF⁺ ion pair production.
