A kinetic study of the isomerization reaction from SSF2 to FSSF using the HeI photoelectron spectroscopic method

The isomerization reaction from SSF2 to FSSF is studied using the HeI photoelectron spectroscopy (PES) method at 23°C and 50°C. This isomerization reaction is found to be first-order. Kinetic equations for the isomerization reaction at the abovementioned temperatures are, respectively: ln R296K=−(3.773±0.387)×10−5 t−1.840 and ln R323K=−(8.547±0.978)×10−5 t−1.927. The activation energy obtained by the PES experiment is 24.078 kJ mol−1.
