Free NMR spectra database

Spectral Database for Organic Compounds SDBS a better place to download most of standard NMR (Nuclear Magnetic Resonance) spectroscopy spectrum for your analysis purposes. It is provide by National Institute of Advanced Industrial Science and Technology (AIST), Japan. The FTIR section managed by T.Yamaji, T.Saito, K.Hayamizu, M.Yanagisawa and O.Yamamoto

Measuring conditions of 1H NMR
1H NMR was measured with a JEOL FX-90Q (89.56 MHz), a JEOL GX-400 (399.65 MHz), or a JEOL AL-400 (399.65 MHz). The measuring conditions for the most of the spectra were as follows: flip angle of 22.5-30.0 degrees, pulse repetition time of 30s. (More information can be obtain from their website)

Measuring conditions of 13C NMR
 13C NMR was measured with a NEVA NV-14 (15.087 MHz), a JEOL FX-90Q (22.530 MHz), a Varian XL-100 (25.160 MHz), a Bruker AC-200 (50.323 MHz), a JEOL FX-200 (50.183 MHz), a JEOL GX-400 (100.535 MHz) or a JEOL AL-400 (100.40 MHz). The measuring conditions for the most of the spectra were as follows: a pulse flip angle of 22.5 - 45 degrees, a pulse repetition time of 4-7 seconds, and a resolution of 0.025-0.045 ppm.
