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 |

Condensed Phase Spectrum
Notice: This spectrum may be better viewed with a Javascript and HTML 5 enabled browser.
Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. More information on the manner in which spectra in this collection were collected can be found here.
Notice: Concentration information is not available for this spectrum and, therefore, molar absorptivity values cannot be derived.
