A Periodic Table of the Elements at Los Alamos National Laboratory
Periodic table site. Gives basic information for each element, including history, properties, sources, uses and cost. Also contains a brief introduction to using the periodic table.
American Chemical Society Home Page
Organizational Web site providing information on educational resources, careers and employment information, and other chemistry sources.
Portal to chemistry resources on the Web, including links to discussion group (ListServs), conferences, biographical and personal sites, and other portals.
Search engine for chemical information on the Web as well as a database of physical property data and 2D chemical structures for common compounds.
Chemical Consultants Network
Directory Web site. Provides contact information, specialty areas and previous experience for consultants in a number of chemistry related fields. Search for consultants by specialty, by keyword or by name.
Chemistry: WebElements Periodic Table
Periodic table site. Provides enhanced information relating to the periodic table and its elements, including history, uses, geological and biological information, basic reactions, electronic, physical and nuclear properties. Bibliographies for further information can also be found in many entries.
This site requires registration but contains some useful tools for chemistry research. Includes access to Beilstein Abstracts (1980 - present), an important index of organic chemistry journals, and an online magazine called The Alchemist.
Links for Chemists / Virtual Library Chemistry Section
Portal to chemistry resources on the Web, including links to academic departments from around the world, company and industry information, chemical literature, software, organizations and employment information.
Molecular Expressions: Images from the Microscope
Subject specific site covering every aspect of microscopes and microscopy. Includes tutorials and primers with, for example, information about optical microscopy, how to set up a microscope, how to take photomicrographs, scanning electron microscopy, and a profusion of images. Look for student activities and teacher resources.
NIST Chemistry WebBook
This site is maintained by the National Institute of Standards and Technology. It provides a database of chemical and physical property data for chemical species. Search options include searching by formula, name, CAS registry number, author, structure and even molecular weight.
PubMed gives free access to citations from MedLine, for medical research, but is also a good resource for organic chemistry articles. MEDLINE indexes many journals which are not strictly medical journals (i.e. Science, Nature, Journal of Organic Chemistry), but removes articles which are not topical; in PubMed even non-topical articles are retained, although not indexed.
This resource allows searching of a number of online databases simultaneously, including Beilstein Abstracts (important organic chemistry index) and the Chemistry Preprint Server. From the homepage, click on "advanced search" to see scope of this resource.
