ATcT [1, 2] enthalpies of formation based on version 1.122d of the Thermochemical Network [3]

Below is a list of 0 K and 298.15 K enthalpies of formation for all 1414 species included in version 1.122d (as of 12/09/2015).
This version of ATcT results was generated from an expansion of version 1.122b [4][5] to include the enthalpies of formation of methylamine, dimethylamine and trimethylamine that were used as reference values to derive the bond dissociation energies of 20 diatomic molecules containing 3d transition metals.[6].

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.)

The reaction search accepts only the preferred formula, as specified in this version of the Thermochemical Network.
For help finding the current preferred formula of a species, please refer to the species name or species formula searches above.
For convenience clicking the preferred formula adds it to the species list for reaction searches.
The stoichiometry represents fractions as decimals,
e.g. 0.5 O2, 1 H2, 1 H2O would represent
1/2 O2 + H2 → H2O
