An Index of Selected Thermodynamic and Physical Property Resources ThermoDex contains records for selected printed and web-based compilations of thermochemical and thermophysical data for chemical compounds and other substances. You can select one or more compound types and link them to one or more property terms, and ThermoDex will return a list of handbooks that could contain these data. Due to copyright and technical considerations, the actual data are not contained in ThermoDex. ThermoDex is based primarily on the holdings of the Mallet Chemistry Library at the University of Texas at Austin. Links are provided to identify library holdings in your area.
