The JESS Thermodynamic Database of chemical reactions is one of the thermodynamic databases in the ‘Joint Expert Speciation System’ (JESS), a package of software and databases concerned primarily with the modelling of chemical phenomena in water solutions. JESS is now the world’s largest single electronic repository of thermodynamic information relevant to such systems.

The chemical reaction database is available here as a set of PDF files. It has been subdivided by chemical elements. Elements are indicated by the initial letter(s) of the PDF file names. To find a chemical reaction of interest, search first for a chemical species, identifying the JESS symbol for it using the S file corresponding to the most relevant element, and then locate all chemical reactions with that JESS symbol in them, by searching through the element’s corresponding R file. A full description of the data in the PDF files is given in the accompanying Zenodo file named ‘Instructions’. It is advisable to read the preamble documents.

The JESS chemical reaction database continues to be developed so feedback is most welcome. Questions concerning the production of the PDF files should be directed to Josep Bonet (josep.bonet@schema.lu) and concerning the content of the database to either or both Peter May (P.May@murdoch.edu.au) and Montserrat Filella (montserrat.filella@unige.ch).
