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.
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
shall not be liable for any damage that may result from errors or omissions in
the program and database.
