Recommended Web Sites for Spectra and
Spectrum-related Information
This site includes information on a wide range of spectroscopy topics, including NMR, IR, UV and mass spec. Access to some features, such as the online e-zine Spectral Lines, requires (no-cost) registration. This site includes discussion forums and links to other spectroscopy-related websites, including online databases of spectral data.
This site can be searched by "lines" (Spectral lines and associated energy levels) or "levels" (energy levels), and also includes a table of ground states and ionization energies for neutral atoms. [Produced by the National Institute of Standards and Technology (NIST)].
Includes IR, mass spec, and UV spectra for thousands of compounds. Scroll down to "Documentation."
Maintained by the Japanese National Institute of Advanced Industrial Science and Technology, this database includes NMR, IR, and MS data for tens of thousands of compounds. Access is free. The providers request that users not download more than 50 files per day, and that you acknowledge them if any data are used in a publication or presentation.
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.
