Spectral Database for Organic Compounds, SDBSProduced by the Japanese National Institute of Advanced Industrial Science and Technology (AIST), SDBS is an integrated spectral database system for organic compounds,which includes 6 different types of spectra under a directory of the compounds. The six spectra are as follows, an electron impact Mass spectrum (EI-MS), a Fourier transform infrared spectrum (FT-IR), a 1H nuclear magnetic resonance (NMR) spectrum, a 13C NMR spectrum, a laser Raman spectrum, and an electron spin resonance (ESR) spectrum. It is possible to search by compound name, molecular formula, molecular weight, CAS Registry Number, number of atoms, and spectral peaks.
