The CNMR Organic Compounds collection contains 11,828 CNMR full spectra and chemical structures. The spectra have been measured at 75 MHz. There are no assignments of spectral to structural features.

In addition to structural formula and spectrum, the following information is available:

• Chemical name
• Molecular formula
• Molecular weight
• Source reference
• Solvent
• Standard
• Measurement conditions

The SpecData collection is only available in JCAMP format
