Electron affinity of neutral species
| EAneutral (eV) | Method | Reference | Comment |
|---|---|---|---|
| <0.599986 | EIAE | Harland and Thynne, 1970 | From (CF3)2CO. Values unreasonable: ΔHf(CF3CO-)must be less than ΔHf(CF3-+CO)=-181. G3MP2B3 EA = 1.6 eV |
Protonation reactions
C2F3O- + = C2HF3O
By formula: C2F3O- + H+ = C2HF3O
