Chemistry
Molecular Structure and Property Databases
- Chemicool Periodic Table - All the basic information about each element, by name, formula, or by clicking on it in a map of the periodic table. VERY USEFUL!
- NIST Chemistry WebBook - This site provides thermochemical, thermophysical, and ion energetics data compiled by NIST under the Standard Reference Data Program. Users can search by molecule name, formula, or CAS number. Standard results include formula, structure, weight, CAS number, and often also various spectra, phase data, and thermochemical data as well. VERY USEFUL!
- Molecule of the Month - "Each month a new molecule will be added to the list on this page. The links will take you to a page at one of the Web sites at a University Chemistry Department or commercial site in the UK, the US, or anywhere in the world, where useful (and hopefully entertaining!), information can be found about a particularly interesting molecule." There doesn't seem to be any logical order of the molecules, but you might find something cool. Goes back to January 1996.
- WebElements - The periodic table on the Web, by Mark Winter of the University of Sheffield, England. This has more in depth information (and cartoons!) about each of the elements, including spectra, crystal structures, uses, and reactions. VERY USEFUL!
- ChemViz - "Short for Chemistry Visualization, this is a set of WWW-based applications created by NCSA designed to catalyze a better understanding of chemical processes through visualization. Two tools are currently supported: Waltz, which generates images and animations of desired molecules and ions; and CSD, which presents a three-dimensional model of complex organic compounds." You will need a login and password to use the programs; signing up for a password is free, or you can use the library's: login is chemlib and the password is Pt48zDZ4 (it is case sensitive).
