Finding thermochemical properties in the literature

The first place that one should generally look for thermochemical data is in the NIST Chemistry Web Book [24], available at http // webbook.nist.gov. This database contains thermochemical properties for more than 7000 small organic and inorganic compounds, and includes the entire contents of several other databases. Table 5 shows the enthalpies of formation and standard entropies of the species from the reaction mechanism in Table 4 that are available in the NIST WebBook. These properties were available for 10 of the 15 species. The source cited in the NIST WebBook for all these species was the NIST-JANAF Themochemical Tables [25], which have long been the first choice for finding thermochemical data for inorganic and very small organic 

Another valuable source is the thermochemical property database assembled by Burcat and Ruscic [29], which is available online at ftp // ftp.technion.ac.il/pub/supported/aetdd/thermodynamics/. This collection is regularly updated by Prof. Burcat. It contains data for 1500 species, presented in the form of polynomial coefficients that can be used to compute the enthalpy, entropy, and heat capacity as a function of temperature. While Burcat s tables include a number of aluminum-oxygen compounds, they do not happen to include the aluminum-chlorine species that we have been using as an example. Of course, there are many other handbooks and compilations of thermodynamic properties. However, the vast majority of these focus on organic compounds and/or condensed phase species. Standard handbooks, such as the CRC Handbook of Chemistry and Physics, rarely have any information not included in the sources cited above.
