There are separate categories for many different branches of science. Please submit your site to the most appropriate category. Submitting to an incorrect category may delay review of your site.
Please submit only websites that have English language content to this category and its subcategories. If your site is in a language other than English, please submit it to the appropriate category of World.
This category is for sites about university departments doing scientific research and providing scientific educational programs in chemistry.
Please try to submit your site to the most appropriate sub-category.
Science/Chemistry/Analytical contains links to those sites which may deal with the facet of chemistry used in the commercial world of chemical analysis. Agricultural, environmental, materials, QA/QC, and forensic links would be some of the most noted topics falling into this category. Pure and applied methods development for analytical processes are also included.
Catalysts are materials that promote or accelerate a chemical reaction, by associating with one or more of the reacting chemicals, and thereby lowering the energy barrier for reaction to occur. The association can be by adsorption or chemisorption (as is the case for solid, heterogeneous catalysts) or by complexation or coordination (as is the case for homogeneous catalysts, including enzymes). Catalysts can repeatedly promote the same reaction, without themselves being converted. The science of catalysis involves itself with developing new or improved catalysts, and with understanding the fundamental processes involved with catalytic reactions.
These are sites that provide information, or data on chemical safety. This will include lab safety, as well as chemical plant and refinery safety sites. Safety equipment and devices will also be included, or at least links to them. Sites more appropriate for high school or younger students will be found in Reference/Education/School_Safety/Labs_and_Experiments/ 4/17/00

Sites here specialize in structure-activity relationships with particular regard for their biological properties, and application in medicine.
Sites focusing on chemical pathology or clinical chemistry should be submitted to the most appropriate subcategory for Clinical Biochemistry.

The terms Medicinal Chemistry and Pharmaceutical Chemistry are used in different countries to cover the interdisciplinary theories, methods and techniques of drug design. This involves the identification, synthesis and development of new chemical structures, or formulations of existing drugs, to improve therapeutic efficacy, bioavailability, mitigate side-effects, or overcome intellectual property issues.

Sites describing software packages should be submitted to Science: Chemistry: Software.
Computational chemistry involves the use of computers to investigate the structure and properties of atoms, molecules, and molecular aggregates. There is great overlap and some confusion between the disciplines commonly called "computational chemistry", "molecular modeling", and "theoretical chemistry". To simplify, all of these are grouped under the computational chemistry ODP category, except for some sites that go to Science/Chemistry/Physical.
Please submit only meetings with a regional, national or international scope and which cover a broad area of Chemistry.
Conferences, courses, meetings, seminars, workshops and other events in Chemistry.
A section for indices of Chemistry resources, most of the sites here should contain indices pointing to at least 500 other chemistry resources
Please submit only sites in English. Sites in other languages should be submitted to the appropriate World category.
Sites that teach or inform about chemistry and chemistry education, from grade school to college. Sites which seek to sell something should have significant, free chemistry education content to contribute.
Electrochemistry is the study of the exchange of electrons between an ion/molecule and an electrode, or another ion/molecule. Application areas include batteries, plating or electrodeposition, corrosion, analytical electrochemistry, as well as the study of any chemical reaction involving oxidation or reduction.
Please submit sites to this category relating to Beryllium and its chemical/physical properties.
Information on the individual elements of, and the groups in which they appear on, the periodic table in the context of the study of chemistry.

Please submit sites promoting consultancy, testing, scientific equipment or supplies, to the appropriate subcategory of Products and Services.

Until it has its own category, sites on development of environmentally friendlier manufacturing processes, Green Chemistry, may be submitted here.  However, sites primarily on issues of pollution, rather than scientific chemistry content, should be submitted to a category linked from Society: Issues: Environment: Pollution.

Environmental chemistry is the study of chemicals, which by their absence or presence in critical amounts, influence life on land and in water.  Environmental chemistry includes the chemicals that influence the levels of critical chemicals such as oxygen and carbon dioxide.  Hence environmental chemistry is concerned with contamination of the atmosphere and water resulting from industrial pollution.  Environmental chemistry includes methods of detection, quantifying the presence, and measuring differences from the natural state, as well as their effects.

This category and its sub-categories includes sites about promoting and aiding this study.

Please submit sites that are related to inorganic chemistry.
The study of all elements and compounds of elements except for carbon.
Please submit your site to the most appropriate category. Submitting to an incorrect category may delay review of your site.
Please submit only websites that have English language content to this category. If your site is in a language other than English, please submit it to the appropriate category of World.
Current news and features about chemistry.
English sites only !
This category is concerned with NMR, EPR, MRI and NQR. There are categories for user guides, commercial vendors of NMR systems and supplies, NMR theory, magnet safety, shimming, in short nearly everything to do with the use, repair and operation of a NMR, EPR, MRI or NQR system. 07/23/00
For sites that are related to organic chemistry. Please submit to the most appropriate subcategory.

If the contents of your web site are not offered in English, then please submit to a suitable category in the proper language in World.

Thank you.

Organic Chemistry is the branch of chemistry dealing with the compounds of carbon.
Please submit only websites that have English language content to this category and its subcategories. If your site is in a language other than English, please submit it to the appropriate category of World.
Organizations are groups of people working together towards a common goal.
URL''s that are submitted to this directory should link directly to the page containing the periodic table. No lists or directories please. URL''s that are for pages that are lists or directories to more periodic tables and do not contain their own periodic table should be submitted to: "Science: Chemistry: Internet Directories."
A selection of sites containing online versions of the periodic table of elements. Sites are classified according to the number of properties they display:
  • Very Basic: less than eight properties.
  • Basic: 9 - 16 properties.
  • Detailed: 17 - 24 properties.
  • Comprehensive: 25 - 32 properties.
  • Very comprehensive: more than 32 properties.

There are also notes when special software or browser features such as JavaScript are required.

Please submit your English language sites here. All non-English sites should be submitted to the World categories.

Please submit all industrial chemical supply sites to

Chemical Suppliers

There is currently no description created for this category.
This category contains sites from research groups mainly interested in various aspects and facets of chemistry. This may include but is not limited to link lists, research and information pages, pages concerning a single element (such as Boron).

Please submit to the most appropriate subcategory. Only those sites which deal with chemical software in general or which cover several categories will be included in the top of Science/Chemistry/Software/.

Directories (that is, sites which contain many links but no chemistry software of their own) should be submitted to the Internet Directories subcategory.

This category lists software used in Chemistry. This includes chemical engineering software, visualization software, chemical database software and specialized types of chemical software.
