NIST Standard Reference Database 202 Web Thermo Tables (WTT) - Lite EditionRate our Products and Services Various search options based on compound information (empirical formula, partial name, molecular weight) are provided. 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. Unlimited data retrieval and their local storage and use are permitted. For details regarding analytical methods and interacting with the interface, see the site user's guide. Evaluated properties that appear in the WTT are (note that all listed properties are not necessarily available for all included compounds): Critical Properties
Phase Transition Properties Triple point temperatureBoiling point Vapor pressure Sublimation pressure Condensed-phase boundary pressure Enthalpy of vaporization Enthalpy of fusion Enthalpy of crystalline phase transitionVolumetric Properties Mass densityEnergetic Properties Enthalpy of formationTransport Properties Additional Properties
