Chemistry World is the print and online magazine of the Royal Society of Chemistry, the largest organisation in Europe for advancing the chemical sciences. With news, features, opinion, podcasts and the latest job advertisements, it's the best way to keep up to date with the global chemical sciences community.
From the Royal Society of Chemistry, ChemSpider is a free chemical structure database providing fast access to over 40 million structures, properties, and associated information. By integrating and linking compounds from ~500 data sources, ChemSpider enables researchers to discover the most comprehensive view of freely available chemical data from a single online search.
The NIST WebBook collects data from many various databases and compilations prepared by the National Institute of Standards and Technology. NIST data are critically evaluated and highly reliable. Properties include gas phase and liquid phase thermochemistry, phase change, reaction thermochemistry, ion energetics, and spectral data for many organic and inorganic species.
