Sadtler and NIST are, respectively, commercial and US Government based organisations which provide collections of reference spectra. Unknown spectra may be searched against these collections subject to a subscription charge. NIST also permits searching by compound name or structure and from a large database and displays infrared gas spectra and other spectral and physical properties. The infrared gas spectra may be manipulated by scale expansion and other parameter changes. Thermo Electron Corporation are also introducing spectral data and libraries
