Thermophysical and Thermochemical
NIST has a long history as the source for reliable thermochemical data starting from the 1920s with the International Critical Tables. The tradition continues as new NIST databases on thermochemical properties of inorganic and small organic molecules gain acceptance.
NIST thermochemical databases are available both in convenient PC formats and as online systems, notably the NIST Chemistry WebBook which has extensive thermochemical data for over 7,000 organic and small inorganic compounds. It also has reaction thermochemistry data for over 8,000 reactions and ion energetics data for over 16,000 compounds.
