ΔfH°gas | 211. | kcal/mol | Review | Roux, Temprado, et al., 2008 | There are insufficient literature values to properly evaluated the data and measurements are of low quality and/or there is substantial disagreement with values predicted using thermochemical cycles or estimation methods (trends). The value is substantially depended upon an estimate with a low degree of confidence. |

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.
