Quantity Value Units Method Reference Comment
Δfgas276.1 ± 5.0kJ/molReviewRoux, Temprado, et al., 2008There are sufficient literature values to make a qualified recommendation where the suggested value is in good agreement with values predicted using thermochemical cycles or from reliable estimates. In general, the evaluated uncertainty limits are on the order of (2 to 4) kJ/mol.; DRB
Quantity Value Units Method Reference Comment
gas541.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 (549-568 J/mol*K [85MAR/LOE, Dorofeeva O.V., 1997]). Value obtained from calorimetric data (722.7 J/mol*K [85MAR/LOE]) authors do not regard as reliable.; GT
