ATcT [1, 2] enthalpies of formation based on version 1.202 of the Thermochemical Network [3]

Below is a list of 0 K and 298.15 K enthalpies of formation for all 3384 species included in version This version of ATcT results[3] was generated by additional expansion of version 1.176 in order to include species related to the thermochemistry of glycine[4].

The elements in their standard states are listed first; the listing order of the other species follows the actual order from the ATcT solution file, which roughly reflects the number of thermochemically-relevant determinations that include the species in question (highest first). The intent is to convey a very approximate indication of the robustness of the listed values, which is generally higher toward the top of the list and lower toward the bottom.

For species other than elements in their standard states, the Species Name acts as a link to the page itemizing the most important contributors to the provenance of its ATcT enthalpy of formation, other highly correlated chemical species, and high-leverage reactions in the Thermochemical Network.
(Please note that, as opposed to traditional sequential thermochemistry where the provenance of a given enthalpy of formation is typically a single measurement, the provenances of ATcT enthalpies of formation, which are obtained by analysing and solving a large Thermochemical Network, are normally quite distributed.)

Formula
The aggregate state is given in parentheses following the formula, such as: g - gas-phase, cr - crystal, l - liquid, etc.

Uncertainties
The listed uncertainties correspond to estimated 95% confidence limits, as customary in thermochemistry (see, for example, Ruscic [5] and Ruscic and Bross[6]).
Note that an uncertainty of ± 0.000 kJ/mol indicates that the estimated uncertainty is < ± 0.0005 kJ/mol.
