Selected ATcT [1, 2] enthalpy of formation based on version 1.156 of the Thermochemical Network [3]This version of ATcT results[3] was generated by additional expansion of version 1.148 to include species relevant to a recent study of the oxidation of ethylene [4] as well as new measurements that led to refining the thermochemistry of CF and SiF and their cations [5]. |
