The NIST-JANAF Thermochemical Tables website is on an online resource that contains the contents of the NIST-JANAF Thermochemical Tables printed volumes. This website is a resource for sharing the data from the work that went into producing the volumes, not as a resource for the most up-to-date thermochemical data available. This is intended as a historic archive for an incredibly valuable resource that continues to have value today.

Diatomic Spectral Database, Triatomic Spectral Database and Hydrocarbon Spectral Database. Each of the databases covers primarily the microwave region with some data available for the radio frequency region. Rotational spectral lines for 121 diatomic molecules, 55 triatomic molecules, and 91 hydrocarbon molecules have been tabulated. The isotopic molecular species, assigned quantum numbers, observed frequency, estimated measurement uncertainty, and reference are given for each transition reported. The spectral lines for many molecules and normal isotopic species have been refit to produce a comprehensive and consistent analysis of all the data extracted from various literature sources. The derived molecular properties, such as rotational and centrifugal distortion constants, hyperfine structure constants, electric dipole moments, rotational g-factors and internuclear distances (for diatomic molecules) are listed with one standard deviation uncertainties for all species.

NIST supports accurate and compatible measurements by certifying and providing over 1300 Standard Reference Materials with well-characterized composition or properties, or both. These materials are used to perform instrument calibrations in units as part of overall quality assurance programs, to verify the accuracy of specific measurements and to support the development of new measurement methods.

The NIST X-ray Photoelectron Spectroscopy (XPS) Database gives easy access to the energies of many photoelectron and Auger-electron spectral lines. Resulting from a critical evaluation of the published literature, the database contains over 29,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. A highly interactive program allows the user to search by element, line type, line energy, and many other variables. Users can easily identify unknown measured lines by matching to previous measurements.

NoRa is a search tool for standards with occupational health and safety (OH&S) relevance that has been available online since the end of 2002. Based on a database of "standards with OH&S-relevant content", it is possible to search specifically for OH&S aspects in standards. The database, which is updated monthly, currently contains some 4900 standards. In the case of withdrawn standards, only standards in the month of their withdrawal are displayed.
