SDBS is an integrated spectral database system for organic compounds, which includes 6 different types of spectra under a directory database of the compounds. The spectra are EI mass, 1H decoupled 13C NMR, 1H NMR pattern (90 and/or 400 MHz), 1H NMR parameter (300 MHz pattern generated), FT-IR, laser-Raman, and ESR. We started the studies on the spectral database system in early 1970. The construction of the database in the present format was started in 1982 in a main-frame computer which was finished at the end of March, 1999. At present, the activities to add new data and update the previous data are still continuing using WS or PC. The numbers of the data for each type of spectra at the end of March, 1999 are as follows.
MS (ca 19,600 spectra)
13C NMR (ca 11,000 spectra)
Compound Dictionary 1H NMR (ca 13,500 spectra)
(30,000 compounds) IR (ca 47,300 spectra)
Raman (ca 3,500 spectra)
ESR (ca 2,000 spectra)
Most of the spectra are measured in their Institute. The master files of the MS, 1H NMR-pattern, IR and Raman spectra are constructed by direct transfer of the digital data from the spectrometers. All the databases contain the spectral patterns. The compounds are mainly obtained from commercial sources and two thirds of the organic compounds in SDBS have between 6 and 16 carbon atoms. Many compounds were gifts from Tokyo Kasei Kogyo Co., Tokyo.
users not allowed to download more than 50 spectra and/or compound structure files in one day.
when the database data is used in a publication or presentation, a proper acknowledgement should be given such as:
