The NIAIST website contains a vast number of spectra for downloading and reproduction. It contains:
(a) 47300 ir spectra;
(b) 13700 1H-nmr spectra;
(c) 11800 13C-nmr spectra;
(d) 20500 ms data;
(e) 3500 Raman spectra;
(f) 2000 esr spectra.
Access to the database and reproduction of the spectra are free of charge, but users are requested not to download more than 50 spectra per day.
The EPA publishes laboratory analytical methods used by industries and municipalities to analyse the chemical and biological components of waste water, drinking water, sediment, and other environmental samples that are required by EPA regulations under the authority of the Clean Water Act and the Safe Drinking Water Act.
Chemfinder indexes many hundreds of websites that contain free chemical and spectroscopic data. It is possible to search the site using CAS Registry numbers, the most effective means of searching for any chemical substance.
