This database contains over 22,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron spectral lines, and is searchable by element, line type, line energy, and many other variables.
Starting Friday October 27, XPS will be down for a few weeks for extended maintenance. NIST X-ray Photoelectron Spectroscopy Database Changes in H and G can be predicted for any reactions among the chemical species. This database provides tables of enthalpies (H) and Gibbs energies of formation (G) for more than 1,000 chemical species in solid, liquid, and gas phases. This database can be used to calculate photon cross-sections for scattering, photoelectric absorption and pair production, and total attenuation coefficients, for any element, compound, or mixture (Z ≤ 100), at energies from 1 keV to 100 GeV. NIST XCOM: Photon Cross Sections Database
NIST peptide libraries are comprehensive, annotated mass spectral reference collections for various organisms and proteins useful for the rapid matching and identification of acquired tandem mass spectrometry (MS/MS) spectra. NIST Libraries of Peptide Fragmentation Mass Spectra Database A catalog of NIST’s free, web interface SRD databases is given below.
