| ΔrH° | 259. ± 21. | kJ/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.; B |
