A directory of chemical resources on the Internet.

A rich collection of chemistry and related sites from online journals, software, to chemistry teaching and learning aids, chemicals, safety, magnetic resonance-NMR, physical constants chemists’ address/phone book, and e-mail. The site features both English and German languages. The department of biology, chemistry, and pharmacy of the Institute of Chemistry Freie Universität of Berlin prepared and maintains this index.

Links for Chemists is an index of chemistry resources on the web. This site is the copyright of The University of Liverpool, Department of Chemistry.

(JenaLib) is aimed at a better dissemination of information on three-dimensional biopolymer structures with an emphasis on visualization and analysis. It provides access to all structure entries deposited at the Protein Data Bank (PDB) or at the Nucleic Acid Database (NDB).

Compiled and maintained by Gary Wiggins of Indiana University as a major part of CHEMINFO, this site includes links to factual chemistry Internet resources and is organized into five main topics: Communication in chemistry, How and where to start, How and where to search: general, How and where to search: specialized, and Miscellaneous.

Welcome to the world of symmetry! The resources contained within this web site are designed to help students learn concepts of molecular symmetry and to help faculty teach concepts of molecular symmetry. The materials are designed for a variety of levels, so look around and see what we have to offer.

XCITR is a collaborative project that allows for sharing of teaching materials relating to the area of chemistry.

This National Institute of Standards and Technology has a searchable and browsable list of the important physical constants with bibliography, as well as a thorough description of the SI system of units and a description of methods of expressing degree of uncertainty in measurements.

This collection of laws, rules and constants in physics, compiled by Erik Max Francis, includes a number of interest in physical chemistry, e.g. the gas laws, Rydberg formula, etc.

WebElements is a hypertext-linked collection of property data on the first 112 elements (and growing...) including (where available): general, chemical, physical, nuclear, electronic, biological, geological, crystallographic, reduction potential, isotopic abundances, electronic configurations, ionization enthalpy data and additional textual information, especially on the history of the elements.

The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.
