Physics and Astronomy: Physical Properties

The National Institute of Standards and Technology (NIST) reference on constants, units, and uncertainty. This site contains CODATA internationally recommended values of the fundamental physical constants.

This list from the National Institute of Standards and Technology (NIST) is a guide to many free, specialized databases, such as spectra, solubility, physical, thermodynamic data, kinetics, and other specialized and advanced databases.

In this NIST SOURCE Data Archive from the Thermodynamics Research Center (TRC) you can find thermophysical and thermochemical property measurements for thousands of pure compounds and mixtures, and then be able to prepare easy to read reports containing this data. Clicking "Demonstrations" on this home page gives you short, easy to follow animated demonstrations of how to use this tool.

Access to the energies of many photoelectron and Auger-electron spectral lines from a critical evaluation of the published literature. This database contains over 22,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines.

The WebBook produced by National Institute of Standards and Technology provides access to well-documented thermodynamic, spectral, and reaction data for thousands of compounds. Often a good starting point.

From the Thermodynamics Research Laboratory of the University of Illinois. This site lists many data sites, and calculation and program download sites in nano, quantum and statistical mechanics and thermodynamics.

Originally published by Smithsonian Institution Press in 1954, this classic reference source comprises 901 tables of common physical and chemical data.

An index to over 120 printed handbooks and compilations of thermodynamic data for elements and compounds. Several of these handbooks are in the Science/Engineering Library. You enter a type of substance and the property or properties you desire, and you will receive a list of handbooks that might contain that data.

Thermophysical property data for thousands pure compounds and mixtures. Part of their data is available for free.

Data for many common solids, liquids, and gases.

Data compiled by Shuzo Ohe from the University of Tokyo.

UV to mid-infrared 0.2-150 micron reflectance spectra of over 1300 minerals, organic and volatile compounds, vegetation, and man-made materials. Also included are mid-infrared data and additional visible and near-infrared spectra.

A multivolume work containing a vast amount of physical property data on thousands of substances. We also have the printed version of these tables in the Science/Engineering Library Reference Section: Q199 N32.

QC61 .L332 (Reference, Section). Contains molecular constants, density, surface tension, dielectric constants, refractive index, vapor pressure, phase transition temperatures and transition enthalpies. In total, 16,897 compounds with 33,828 references to numerical data are recorded.

QD511 .N57 1998g (Reference Section). Tables of recommended temperature-dependent values for the standard enthalpy of formation, Gibbs (free) energy of formation, the logarithm of the equilibrium constant of formation and more.

Physical property data is often buried within the primary literature and not retrievable by searching databases. This three volume set Z5853.M38 P8 1967 (Reference Section) contains this often difficult to obtain data for many substances. http://www.istl.org/12-fall/viewpoint.html discusses this useful physical data source.

QD503 .G59 (Reference Section). Tables and diagrams of data for binary and multicomponent mixtures up to moderate pressures.
