NIST/TRC Web Thermo Tables (WTT)
NIST Standard Reference Subscription Database 3 - Professional Edition
Version 2-2012-1-Pro
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
[1, 2, 3, 4, 5, 6].
Some critically evaluated data
from the historical
TRC Thermodynamic Tables archive
[7, 8] are included, also. As of May 2012, the Professional Edition contains information on 28432 compounds and total of 531486 evaluated data points.
The properties covered by both versions (32 total) are described in Properties and Implemented Models.
Developed by Kenneth Kroenlein, Chris D. Muzny, Andrei F. Kazakov, Vladimir Diky,
Robert D. Chirico, Joseph W. Magee, Ilmutdin Abdulagatov and Michael Frenkel.
DISCLAIMER: The National Institute of Standards and Technology (NIST) uses its
best efforts to deliver a high-quality copy of the database and to verify that the
methods and data contained therein have been selected on the basis of sound
scientific judgement. However, NIST makes no warranties to that effect, and NIST
