of CF3CHF and CF3 radicals at room temperature generated chemicallyactivated CF3CHFCF3 molecules with 95 ± 3 kcal/mol of internal energy that decompose by loss of HF, initially attached to adjacent carbons, with an experimental unimolecular rate constant of (4.5 ± 1.1) × 102 s−1. Density functional theory was used to model the unimolecular rate constant for HF elimination, kHF, to determine a threshold
