Selected ATcT [1, 2] enthalpy of formation based on version 1.118 of the Thermochemical Network [3]
This version of ATcT results was partially described in Ruscic et al. [4],
and was also used for the initial development of high-accuracy ANLn composite electronic structure methods [5].

Top contributors to the provenance of ΔfH° of HNO3 (g)The 16 contributors listed below account for 90.2% of the provenance of ΔfH° of HNO3 (g).
Please note: The list is limited to 20 most important contributors or, if less, a number sufficient to account for 90% of the provenance. The listed Reaction acts as a link to the relevant references for the measurement. The Measured Quantity is normaly given in the original units; in cases where we have reinterpreted the original measurement, the listed value may differ from that given by the authors. The quoted uncertainty is the a priori uncertainty used as input when constructing the initial Thermochemical Network, and corresponds either to the value proposed by the original authors or to our estimate; if an additional multiplier is given in parentheses immediately after the prior uncertainty, it corresponds to the factor by which the prior uncertainty needed to be multiplied during the ATcT analysis in order to make that particular measurement consistent with the prevailing knowledge contained in the Thermochemical Network.
