SDBS includes 14700 1 H NMR spectra and 13000 13 C NMR spectra as well as FT-IR, Raman, ESR, and MS data. The data are stored and displayed as an image of the processed data. Annotation is achieved by a list of the chemical shifts correlated to letters which are also used to label a molecular line drawing.

If a spectrum of an unknown chemical compound is available, a reverse search can be carried out by entering the values of the chemical shift, frequency or mass of the peaks in the NMR, FT-IR or EI-MS spectrum respectively. This type of search affords all the chemical compounds in the database that have the entered spectral characteristics. [6]
Greylag is a database search algorithm developed at the Stowers Institute for Medical Research designed to perform large searches on computational clusters containing hundreds of nodes. InsPecT Open source: InsPecT is an MS-alignment search algorithm developed by the Center for Computational Mass Spectrometry at the University of California ...
The database contains also a smaller amount of NMR data from carbohydrates, cofactors and ligands. [1] These data are crossreferenced to 3D structures in the PDB when available. The NMR data are provided in the NMR-STAR file format and a number of format conversion tools are available at the site to convert files from NMR-STAR to other formats. [1]
All chemical shifts in RefDB have been computationally re-referenced to DSS (a common NMR chemical shift standard). [1] RefDB is a continuously updated resource that uses web-bots to query public databases (BMRB, GenBank, Protein Data Bank) and fetch assignment, sequence and structure data on a weekly basis.
Yoshito Kishi's group at Harvard University has reported NMR databases for 1,3,5-triols [1] 1,2,3-triols, 1,2,3,4-tetraols, and 1,2,3,4,5-pentaols. [2] The stereochemistry of any 1,2,3-triol may be determined by comparing it with the database, even if the remainder of the unknown molecule is different from the database template compounds.
Triple resonance experiments are a set of multi-dimensional nuclear magnetic resonance spectroscopy (NMR) experiments that link three types of atomic nuclei, most typically consisting of 1 H, 15 N and 13 C. These experiments are often used to assign specific resonance signals to specific atoms in an isotopically-enriched protein.
