The NIST/TRC SOURCE data archival system is used in conjunction with the ThermoData Engine as a comprehensive storage facility for experimental thermophysical and thermochemical property data for approximately 23,000 pure compounds. This database contains experimental and computed (quantum mechanics) thermochemical data for a selected set of nearly 1,900 gas-phase atoms and small molecules. NIST Computational Chemistry Comparison and Benchmark Database SESSA can be used to simulate Auger-electron spectroscopy and X-ray photoelectron spectroscopy spectra of multilayer thin films and nanostructures such as islands, lines, and spheres on surfaces. NIST Database for the Simulation of Electron Spectra for Surface Analysis (SESSA) This database provides values of electron-effective attenuation lengths in solid elements and compounds at selected electron energies for surface analysis by Auger-electron spectroscopy and X-ray photoelectron spectroscopy. NIST Electron Effective-Attenuation-Length Database REFLEAK estimates composition changes of zeotropic mixtures in leak and recharge processes in industrial applications such as distillation, refrigeration, and cleaning processes. REFLEAK: NIST Leak/Recharge Simulation Program for Refrigerant Blends This database provides values of electron-inelastic mean free paths for elements, inorganic compounds, and organic compounds that are used in quantitative surface analyses by Auger-electron spectroscopy and X-ray photoelectron spectroscopy. NIST Electron Inelastic-Mean-Free-Path Database The Chemistry WebBook provides internet access to a variety of physical and chemical property data on well-defined chemical species and reactions. 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 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 program calculates the thermodynamic and transport properties of industrially important fluids and their mixtures. REFPROP is an acronym for REFerence fluid PROPerties. NIST Reference Fluid Thermodynamic and Transport Properties Database 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. The thermodynamic properties of water, based on international standards over a wide range of conditions, are presented in this database. This database is the product of an ongoing comprehensive evaluation and expansion of the world's most widely used mass spectral reference library. NIST/EPA/NIH Mass Spectral Library with Search Program The Chemistry SRDs are sorted by SRD number (below) and by subtopic.
