Also includes links to other chemical and toxicological databases. A growing database of properties of industrial materials, including densities and other physical properties, as well as mechanical, thermal, and electrical properties. The models can be displayed in a variety of different formats. The entire safety database can be downloaded from the site as a zip file. Energy levels, transition probabilities, and wavelengths for atomic line spectra.
Ionization energies for neutral atoms are also available on a hyperlinked periodic table.
A database of 5000 simple organic compounds, which can be searched by functional group, formula, name, or spectral properties. Entries include density, index of refraction, boiling points, melting points, main mass spectrometry peaks, UV absorption wavelengths and molar absorptivities. A collection of scanned phase diagrams for pairs of elements and for some ternary compounds, ceramics, and oxides. Includes links to sources of software for predicting phase diagrams and thermochemical properties.
