Molecular Visualization Software Eric Martz's site for Chime, Protein Explorer and RasMol software for looking at macromolecular structure and its relation to function
NIST Chemistry Webbook This site provides thermochemical, thermophysical, and ion energetics data compiled by the National Institute of Standards and Technology (NIST) under the Standard Reference Data Program.
SDBS: Spectroscopic Database for Organic Compounds This site, located in Japan, provides a variety of useful spectrosopic data (NMR, IR, MS, UV-Vis, etc.) for a large number of known compounds, free of charge.
NMRDB: A freely available web-based resource for NMR prediction This site can be used to predict 1H NMR for compounds. drawn via the web-based interface. Start by pressing the "NMR Predictor" link, then press "draw molecule" to open a Java-based molecular drawing program. When the molecule is drawn corrrectly, press the "submit" button.
Protein Data Bank The Protein Data Bank (PDB), operated by the Research Collaboratory for Structural Bioinformatics (RCSB), is the single international repository for the processing and distribution of 3D macromolecular structure data primarily determined experimentally by X-ray crystallography and NMR.
Proteopedia: Life in 3D The proteopedia project, hosted in Israel, is a collaborative 3D encyclopedia of proteins and macromolecules, that visually demonstrates the structure and function of these species using literature X-ray crystallographic data.
BenchFly A website dedicated to documenting and sharing scientific protocols by videotaped media.
