Database of Mass, IR, ESR, and NMR Spectra: NIMCR's ISDBS for Organic Compounds
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.

**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.
