NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) Version 9 - SRD 23
Data provided by National Institute of Standards and Technology
**NOTICE: THIS VERSION OF REFPROP (9.1) has been superseded by Version 10: https://doi.org/10.18434/T4/1502528 ** NIST Standard Reference Data 23 contains revised data in a Windows version of the database, including 105 pure fluids and allowing mixtures of up to 20 components. The fluids include the environmentally acceptable HFCs, traditional HFCs and CFCs and 'natural' refrigerants like ammonia. Version9.1 REFPROP 9.1 has replaced the NIST 12 and 14 databases.

NIST Thermophysical Properties of Hydrocarbon Mixtures Database- SRD 4
Data provided by National Institute of Standards and Technology
SUPERTRAPP is an interactive computer program for predicting thermodynamic and transport properties of pure fluids and fluid mixtures containing up to 20 components. The components are selected from a database of 210 components, mostly hydrocarbons. SUPERTRAPP performs phase equilibria calculations and gives the thermophysical properties of all phases and the feed.

NIST/ASME Steam Properties Database - SRD 10
Data provided by National Institute of Standards and Technology
The NIST/ASME Steam Properties Database is based upon the International Association for the Properties of Water and Steam (IAPWS) 1995 formulation for general and scientific use for the thermodynamic properties of water, this updated version provides water properties from the international standards over a wide range of conditions. Version 3.0 incorporates new IAPWS standards adopted in 2008 for the viscosity and for the melting and sublimation curves and in 2011 for the thermal conductivity.

NIST XCOM: Photon Cross Sections Database - SRD 8
Data provided by National Institute of Standards and Technology
A web database is provided which can be used to calculate photon cross sections for scattering, photoelectric absorption and pair production, as well as total attenuation coefficients, for any element, compound or mixture (Z <= 100) at energies from 1 keV to 100 GeV. XCOM provides two forms of output: (a) tables which correspond closely in format to existing tables in the literature; (b) graphical display of the tabular data.

NIST Observed Interstellar Molecular Microwave Transitions Database - SRD 116
Data provided by National Institute of Standards and Technology
This database contains critically evaluated transition frequencies for the molecular transitions detected in interstellar and circumstellar clouds reported in the literature through mid-2008. The tabulated transition frequencies are recommended for reference in future astronomical observations in the centimeter and millimeter wavelength regions. The transition frequencies have been selected through a critical examination and analysis of the laboratory spectral data obtained from the literature.

NIST Electron-Impact Ionization Cross Section Database - SRD 107
Data provided by National Institute of Standards and Technology
This is a database of total ionization cross sections of atoms and molecules by electron impact. The cross sections were calculated using the Binary-Encounter-Bethe (BEB) model, which combines the Mott cross section with the high-incident energy behavior of the Bethe cross section. Selected experimental data are included. Singly differential cross sections are included for H, He, and H2. Electron-impact excitation cross sections are also included for selected atoms.
