NIST Web Thermo Tables (WTT) - Professional Edition - SRD 203

The Web Thermo Tables (WTT) are a collection of critically evaluated thermodynamic property data for pure compounds with a primary focus on organics. These data were generated through dynamic data analysis, as implemented in the NIST ThermoData Engine software package. Also included are some critically evaluated data from the historical TRC Thermodynamic Tables archive. The Professional Edition contains information on over 28,000 compounds. For a subset of the data focused on commonly-used pure compounds please see the Lite Edition (http://www.nist.gov/srd/nistwebsub2.cfm) .
