Spectral Information Resources

Web-Based Spectra Resources available to University of Chicago users (some are free, some are paid subscriptions)

SpecInfo collection from Chemical Concepts/Wiley Interscience (restricted to UChicago)
Spectral Information in Chemistry Databases (restricted to UChicago)
- SciFinder - References and/or spectra images of NMR, IR, Raman, MS, UV/VIS may be included in the "Experimental Properties" portion of the CAS Registry record for the substance
- Beilstein - References to literature reports of NMR, IR, MS, Raman, UV/VIS and other spectral data are often included in the compound record
Other "Free" Spectral Data Collections
- NIST Chemistry WebBook
- Sigma-Aldrich "Catalog"
  (from the list of results, click on the name of the compound, then on the catalog number or CAS RN to see the full record; spectra links (if available are in the box to the right of the main entry under "Related Information")
  NMR, IR, Raman and MS may be available
- EPA Emission Measurement Center Spectral Database (requires a viewer for .spc files like ShowSPC)
  Includes FTIR absorbance spectra, mainly for substances of environmental significance (e.g., common pollutants)
- SDBS (Spectral Database System for Organic Compounds -- 47,000 compounds)
  From NIMC -- National Institute of Materials and Chemical Research, Japan; includes IR, NMR, MS
- NMRShiftDB
  Contains about 25,000 13C, 1H and other nuclei NMR open source spectra of organic compounds
- Mineral Spectroscopy Server (Caltech)
  Includes optical, IR, and Raman spectra of rocks and minerals (inorganic)
