In this database, the primary interactions of x-rays with isolated atoms from Z = 1 (hydrogen) to Z = 92 (uranium) are described and computed. X-ray form factors, attenuation, and scattering tables are widely used in the UV, X-ray and γ-ray communities. NIST X-ray Form Factor, Attenuation and Scattering Tables This database provides values of differential elastic-scattering, total elastic-scattering, and transport cross-sections for elements with atomic numbers from 1 to 96 needed for quantitative analysis by Auger-electron spectroscopy, X-ray photoelectron spectroscopy, electron microprobe analysis, and analytical electron microscopy. NIST Electron Elastic-Scattering Cross-Section Database Thermal, mechanical, and superconducting property data for oxide superconductors, e.g., compounds derived from the Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O, Tl-Sr-Ca-Cu-O, and La-Cu-O chemical families, are provided in this database. This database contains reference functions and tables of thermocouple electromotive force versus temperature for the eight letter-designated thermocouple types: noble-metal types B, R, and S and base-metal types E, J, K, N, and T. This database provides comprehensive coverage of interactions for aqueous systems of organic and inorganic ligands with protons and various metal ions and is based on the six-volume Critical Stability Constants by Martell and Smith. NIST Critically Selected Stability Constants of Metal Complexes This database enables determination of kinetics data on solution-phase reactions through a search form in which reactant(s), product(s), and/or solvent(s) are inputted. This database provides physical properties for major series of compounds derived from the ceramic oxide, carbide, nitride, boride, and oxynitride chemical families used for structural applications such as heat exchangers and engines. 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. 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 You can search for data on specific compounds in the Chemistry WebBook based on name, chemical formula, CAS registry number, molecular weight, chemical structure, or selected ion energetics and spectral properties.A catalog of NIST’s free, web interface SRD databases is given below.
