The greatest technical challenge in the development of the WebBook is the integration of databases from multiple sources into a single collection of data. The many contributors to the WebBook are identified in the "credits" section of the web page at. The site also includes two special features: a set of interactive physical property models developed at the NIST Boulder labs and a group additivity based estimator for gas phase thermodynamic properties. It includes a variety of data from NIST and outside contributors. The NIST Chemistry WebBook was established in 1996 and has grown to encompass a wide variety of thermochemical, ion energetics, physical, solubility, spectroscopic, and chromatographic data.

Data from NIST Standard Reference Database 69: NIST Chemistry WebBook 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 data contained therein have been selected on the basis of sound scientific judgment. Research Activities and Technical Approach Resource provides thermochemical, thermophysical, and ion energetics data compiled by NIST under the Standard Reference. Distribute NIST data for chemical systems in manner that is convenient for NIST's customers.Objectiveĭevelop a web site that provides reliable and convenient access to NIST data on chemical systems. The NIST Chemistry WebBook is intended to help fulfill NIST's mission by distributing such data over the Internet. It is part of NIST's mission to distribute Standard Reference Data to scientists, engineers, educators, and the general public.
