The thermodynamic properties of water, based on international standards over a wide range of conditions, are presented in this database. This database provides the following information for hundreds of polycyclic aromatic hydrocarbon molecules: compound information, 3d models, thermochemistry, and UV-Vis spectra. NIST Polycyclic Aromatic Hydrocarbon Structure Index ILThermo is a database of chemical and physical properties of ionic liquids searchable by means of the ions constituting the ionic liquids, the ionic liquids themselves, their properties, and references.

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 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 The Chemistry WebBook provides internet access to a variety of physical and chemical property data on well-defined chemical species and reactions. This database is the product of an ongoing comprehensive evaluation and expansion of the world's most widely used mass spectral reference library.
