Spectra Information Sources - online

Extensive spectra data can be found for many compounds in SciFinder-n. However, SDBS (below) is also a good, quick starting place.

SciFinder-n: contains over 1.1 million (MS, IR, 13C-NMR, 1H-NMR) spectra based on experimental property data, and more than 55.2 million predicted 13C-NMR and 55.2 million predicted 1H-NMR spectra.


Spectra data sources freely available on the web:

NIST (National Institute of Standards and Technology) Chemistry Workbook: Contains IR, MS, and UV/VIS spectra data.

NMRShiftDB: nmrshiftdb2 is a NMR database (web database) for organic structures and their nuclear magnetic resonance (nmr) spectra. It allows for spectrum prediction (13C, 1H and other nuclei) as well as for searching spectra, structures and other properties. Last not least, it features peer-reviewed submission of datasets by its users. The nmrshiftdb2 software is open source, the data is published under an open content license.

Sigma-Aldrich Catalog: FT-IR Raman, FT-IR Condensed Phase and FT-NMR spectra for some chemicals in the Sigma Aldrich catalog. If spectra are available, you'll find them under the 'Safety and Documentation' tab.

Spectal Database for Organic Compounds: SDBS: Produced 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.
