| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔfH°gas | 95.6 ± 2.6 | kcal/mol | Review | Roux, Temprado, et al., 2008 | There are insufficient literature values to properly evaluate the data and insufficient information to construct thermochemical cycles or estimate values for comparison, and one must rely solely upon reported uncertainities and the quality of the measurements. In general, the evaluated uncertainty limits are on the order of (3 to 9) kJ/mol.; DRB |
| ΔfH°gas | 91.4 ± 1.8 | kcal/mol | Ccb | Balepin, Lebedev, et al., 1977 | ALS |
