NIST Standard Reference Subscription Database 202 Web Thermo Tables (WTT) - Lite Edition

This web application provides access to 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. As of November, 2010, WTT - Lite Edition contains information on 150 commonly-used compounds and access to a total of 86407 evaluated experimental data points.

NIST Standard Reference Subscription Database 203 Web Thermo Tables (WTT) - Professional Edition

This web application provides access to 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. As of November, 2011, WTT - Professional Edition contains information on 23399 compounds and access to a total of 512538 evaluated experimental data points. This product also provides critically evaluated data for some non-molecular species such as radicals and organic salts carried from the TRC Thermodynamic Tables published from 1942-2009.


Update
The NIST Ceramics WebBook was updated July 2015.
