Web Thermo Tables

PURPOSE

WebThermoTables is a web application that delivers the most-up-to-date critically evaluated thermodynamic data, providing a web interface to data from ThermoData Engine.

TRC-wtt-example

Features

  • Data presentation features an interactive JavaScript-based Web interface with dynamic window-in-window navigation.
  • Dynamic table generation based upon user input and interactive data plotting capabilities are also provided.
  • Various search options based on compound information such as: empirical formula, partial name, molecular weight. 
  • Unlimited data retrieval and their local storage and use are permitted.
  • Detailed description of key elements in the experimental investigations such as sample purification and measurement methods
  • Worldwide collection of scientific journals
  • Up-to-date information on major publications

Coverage depends on version

  • WTT PRO

    • A complete collection of critically evaluated thermodynamic property data primarily for pure organic compounds. 
    • As of November, 2011, WTT pro contains information on 23, 399 compounds.
    • Limited data availability information (properties provided for a given compound, ranges of validity, number of experimental data points points) can be accessed by those without a subscription at https://wtt-pro.nist.gov
  • WTT LITE

    • A small collection of critically evaluated thermodynamic property data for 150 commonly used (primarily organic) pure compounds. A complete list of compounds present in the Lite version of the database is provided here
    • Limited data availability information (properties provided for a given compound, ranges of validity, number of experimental data points points) can be accessed by those without a subscription at https://wtt-lite.nist.gov
