Δfgas398.1 ± 6.9kJ/molReviewRoux, Temprado, et al., 2008There 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

gas639.J/mol*KN/AMarcus Y., 1986This value calculated from published spectroscopic and structural data is in close agreement with estimations by a method of increments (654-673 J/mol*K [85MAR/LOE, Dorofeeva O.V., 1997]). Value obtained from calorimetric data (660.6 J/mol*K [85MAR/LOE]) authors do not regard as reliable.; GT
