Useful Links for Chemistry 351

Software Downloads

• Hyperchem Web Viewer  (Needed to view 3-D models, compatible with Interent Explorer only.)
• Molecular weight calculator plug-in for Excel (Great for percent yield calculations.)
• Accelrys Draw (Free molecule drawing software. You will need to register first before downloading.)
• ACD/ChemSketch (Another free molecule drawing software download.)
• Hyperchem (molecular modeling software owned by WSU)

I highly recommend that you download and install Accelrys Draw or ChemSketch. You can use them to prepare more professional looking graphics in lab reports (worth bonus points) and they have some amazing capabilities including IUPAC name generation.

Databases of Physical Constants and Spectra

• CHEMnetBASE. Try the Properties of Organic Compounds database!
• Database of Mass, IR, ESR, and NMR Spectra: NIMCR's ISDBS for Organic Compounds
• This is a service provided by the Japanese National Science Foundation. Since the earthquake/tsunami/meltdown last year the site has intermittent down times.
  
• Sigma-Aldrich is another place to look for NMR and IR spectra: www.SigmaAldrich.com
• After you search the compound click for information on the specific product, then select the "Safety & Documentation". If NMR data is available there will be a link labeled "FT-NMR" in the Documents list.
• C-13 Chemical Shifts: http://www.chem.wisc.edu/areas/reich/Handouts/nmr-c13/cdata.htm
• H-1 Chemical Shifts: http://www.chem.wisc.edu/areas/reich/handouts/nmr-h/hdata.htm
• NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities
  • The above paper, published in J. Org. Chem. in 1997, is number one on the most read articles list for this journal.
• NMR Spectrum Predictor** http://www.nmrdb.org/predictor
  
• C-13 NMR Shift Predictor** http://www.colby.edu/chemistry/PChem/scripts/MarvinWeb/smiBSmarv.html
  **Beware putting too much credence in the NMR predictors. These only predict spectral data based on a relatively small set of known compounds' spectra. The results obtained cannot by any stretch be used as "true",  "literature", or "theoretical" values. However, sometimes they can be used as a "guesstimate" of where your peaks should be.
  
• WSU Spectral Database: Small database of compounds prepared at WSU.
• ChemIDPlus. Detailed toxicity data for 139,000 common compounds.
• http://www.emolecules.com/ Allows one to search for information by drawing the structure of the compound.
• Databases available through the WSU library Includes on-line archive of all ACS journals!
• Five-Ash database of IR spectra. Use the WSU Library Databases link access this database.
• Look up physical constants on-line: CambridgeSoft's ChemFinder
• Database of IR and Mass Spectra. NIST Chemistry WebBook
• Periodic table with links to properties of the elements: Chemicool Periodic Table
• When all else fails try googling it! www.google.com (Actually, you might want to try googling it first!)
