Selected ATcT [1, 2] enthalpy of formation based on version 1.124 of the Thermochemical Network [3]
This version of ATcT results was generated by additional expansion of version 1.122x [4] to include additional information relevant to the study of thermophysical and thermochemical properties of CH2 and CH3 using nonrigid rotor anharmonic oscillator (NRRAO) partition functions [5], the development and benchmarking of a state-of-the-art computational approach that aims to reproduce total atomization energies of small molecules within 10–15 cm-1 [6], as well as the study of the reversible reaction C2H3 + H2 ⇌ C2H4 + H ⇌ C2H5 [7]| Species Name | Formula | Image | ΔfH°(0 K) | ΔfH°(298.15 K) | Uncertainty | Units | Relative Molecular Mass |
