Clustering reactions
+ FPS = F2PS-
| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔrH° | 62.0 ± 5.0 | kcal/mol | IMRB | Larson and McMahon, 1987 | gas phase; These relative affinities are ca. 10 kcal/mol weaker than threshold values (see Wenthold and Squires, 1995) for donors greater than ca. 27 kcal/mol in free energy. This discrepancy has not yet been resolved, though the stronger value appears preferable. |
| Quantity | Value | Units | Method | Reference | Comment |
| ΔrG° | 56.0 ± 4.0 | kcal/mol | IMRB | Larson and McMahon, 1987 | gas phase; These relative affinities are ca. 10 kcal/mol weaker than threshold values (see Wenthold and Squires, 1995) for donors greater than ca. 27 kcal/mol in free energy. This discrepancy has not yet been resolved, though the stronger value appears preferable. |
