| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔrH° | 1539. ± 40. | kJ/mol | D-EA | Desai, Wu, et al., 1996 | gas phase |
| ΔrH° | 1505. ± 17. | kJ/mol | G+TS | Damrauer, Krempp, et al., 1991 | gas phase; Between CF3CH2OH, pyrrole. Calculations imply that the acid is AlOH, not HAlO |
