Sites about chemical businesses or industry are not listed in this category. See Business/Chemicals and Business/Industrial_Goods_and_Services/Engineering/Chemical instead.
Sites about chemical engineering should go to Science/Technology/Chemical_Engineering. |
Chemistry is typically defined as the science that studies the composition, structure, and transformation of matter.It has been called "the central science" because of the way it is related with all the other sciences. Chemistry bridges the gap between physics and biology; it is a "helper science" in almost many technical disciplines; and it occupies a prominent position in industry between the extraction of raw materials and the manufacture of finished products. Of course, it is chemists who call it this way; other scientists may have different perspectives.
Chemistry is also distinguished from some other sciences because it creates its own object of study: chemists can imagine and create new compounds that have never existed in nature, so they are not constrained to what already exists, but only to what can be done.
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 refienery 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

| 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
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.
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 that are related to inorganic chemistry. |
The study of all elements and compounds of elements except for carbon.
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.

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." more information (editors only) |
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.
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 submited 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.
