(a). Fragmentation patterns of the production ions generated from PFHxS molecular ions (m/z 399); (b). Fragmentation patterns of the molecular ions of 3m- and 2m-PFHxS: The arrow marks the missing product ion and the enhanced production ions corresponding to the preferential cleavage near the position of CF3 substitution; (c) proposed mechanism of 1-series product ion at m/z 261.
