Active thermochemical tables: Dissociation energies of several homonuclear first-row diatomics and related thermochemical values

Abstract

The current Active Thermochemical Tables (ATcT) results for the bond dissociation energies of the homonuclear diatomics H2, C2, N2, O2, and F2 are reported and discussed. The role and origin of the distributed provenance of ATcT values is analyzed. Ramifications in terms of the enthalpies of formation of H, C, N, O, and F atoms, which are fundamental thermochemical quantities, are presented. In addition, the current ATcT bond dissociation energies and enthalpies of formation of HF, CH, CO, CN, NO, OH, CO2, H2O, and triplet and singlet CH2 are also reported. © The Author(s) 2013.
