Open Access to the JESS Chemical Reaction Database

The JESS (Joint Expert Speciation System) Thermodynamic Database (v8.9) is now available as a set of freely available PDF files. This reaction database contains about 280,000 thermodynamic parameters (equilibrium constants, enthalpies, etc.) as published in the literature for over 80,000 chemical reactions. It is grounded in the tradition of the Stability Constants Special Publications (by the Chemical Society) but it has become much more extensive and it includes some quantitative indication of parameter reliability based mainly on intra- and extra-reaction consistency.

Automated summary

The JESS Thermodynamic Database (v8.9) is now available as a set of freely accessible PDF files, containing around 280,000 thermodynamic parameters from over 80,000 chemical reactions. It builds upon the Stability Constants Special Publications while offering additional quantitative indicators of parameter reliability based on reaction consistency.
