| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔfH°gas | -276.9 ± 3.1 | kcal/mol | Ther | Larson and McMahon, 1983 | 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. |
| ΔfH°gas | -307.0 ± 5.0 | kcal/mol | IMRB | Galembeck, Faigle, et al., 1978 |
