ThermoDex contains annotated records that describe compilations of thermodynamic and physical property data for chemical compounds and other substances. Most of the compilations included are printed books; some are freely available Web-based databases. ThermoDex is a "finding aid" designed to save you time in searching through numerous handbooks you might have in your library or lab. It enables you to enter both a type of compound and a property, and it the returns a list of handbooks that might contain these data.

В знаменитой серии справочных изданий Ландольт-Бернштейна по численным данным для науки и техники опубликована новая версия Справочника по вириальным коэффициентам, который является продолжением популярного среди специалистов издания J.H.

Справочник включает все опубликованные данные по второму и третьему вириальным коэффициентам неорганических и органических веществ по состоянию на конец 1998 года. Доступ к БД, содержащей электронные версии серии Ландольт-Бернштейна является платным. Предыдущее издание справочника имеется в фондах РГБ и ГПНТБ.

The values of the constants provided at this site are recommended for international use by CODATA and are the latest available. Termed the ""1998 CODATA recommended values,"" they are generally recognized worldwide for use in all fields of science and technology. The values became available in July 1999 and replaced the 1986 CODATA set. They are based on all of the data available through 31 December 1998. A detailed description of the data and the analysis that led to these values may be found in the Journal of Physical and Chemical Reference Data, Vol. 28, No. 6, pp. 1713-1852, 1999 and in the Reviews of Modern Physics, Vol. 72, No. 2, pp. 351-495, 2000.

Founded in 1901, NIST is a non-regulatory federal agency within the U.S. Commerce Departments Technology Administration. NISTs mission is to develop and promote measurement, standards, and technology to enhance productivity, facilitate trade, and improve the quality of life. NIST carries out its mission in four cooperative programs: the NIST Laboratories, conducting research that advances the nations technology infrastructure and is needed by U.S. industry to continually improve products and services

The NASA Scientific and Technical Information (STI) Programs mission is to collect, archive, and disseminate NASA aerospace information, and locate domestic and international STI pertinent to NASAs missions and Strategic Enterprises. Examples of NASAs STI include research reports, journal articles, conference and meeting papers, technical videos, mission-related operational documents, and preliminary data. NASAs technical information is available via the NASA Technical Report Server (NTRS) is to provide students, educators, and the public access to NASAs technical literature. NTRS also collects scientific and technical information from sites external to NASA to broaden the scope of information available to users. NTRSs Simple Search searches for NASA information only and its Advanced Search can search for NASA and non-NASA information. Most of the NASA information does not have full-text document images and documents can be ordered by contacting the NASA Center for AeroSpace Information.
