Index to Physical, Chemical and Other Property Data

This site is an index to resources that contain chemical, physical, thermodynamic, mechanical, toxicological, and safety data. Its heart is an alphabetical listing of properties linked to resources that contain data on that property. Although this site is based on resources in the Arizona State University Libraries, many of the same resources are available to UAlbany users.

ICT contains the best (critical) data derived from the literature up to 1924. It includes data on physical, thermodynamic, mechanical, and other important properties for chemistry, physics, and engineering. The data is presented as text, equations, tables, graphs, and charts. ICT is fully searchable and the index is hyperlinked to the data.

Journal of Physical and Chemical Reference DataAccessible to University at Albany users only

Search for data and properties in the Journal of Physical and Chemical Reference Data.

knovel Critical TablesAccessible to University at Albany users only

Knovel Critical Tables (kCT) are based on the International Critical Tables of Numeric Data, Physics, Chemistry, and Technology, and include up-to-date, evaluated data on over 13,000 compounds. The tables contain data on organic and inorganic compounds, and pure substances. New tables will be added to kCT on a regular basis. kCT is fully searchable.
