Welcome to the ATcT website!

Active Thermochemical Tables (ATcT) are a new paradigm of how to develop accurate, reliable, and internally consistent thermochemical values (such as enthalpies of formation, Gibbs energies of formation, bond dissociation energies, reaction enthalpies, etc.) for stable, reactive, and transient chemical species by utilizing to the fullest all available experimental measurements as well as state-of-the art theoretical data. As opposed to traditional sequential thermochemistry (A begets B, which begets C, etc.), ATcT is based on constructing, analyzing, and solving the underlying Thermochemical Network (TN). The ATcT approach propels thermochemistry to a new orbit by rectifying fundamental deficiencies ingrained in the traditional approach to thermochemistry. It also acts as a unique bridge that efficiently interfaces experiments and theory and integrates the best aspects of both. Finally, ATcT introduce to thermochemistry a number of entirely new capabilities that were never available before.
