The NIST Chemistry WebBook (http://webbook.nist.gov) is an Internet site that provides access to chemical and physical property data both from NIST and other sources. The site was established in 1996 and has grown to encompass a wide variety of
For a binary mixture of a dilute nonvolatile solute in a volatile solvent, an asymptotic expression is derived for isothermal dew-bubble curves in the region just above the solvent critical point. The expression depends only on the solvent coexistence

Theoretical calculations were carried out on the H-atom abstraction reaction from methane by XO (X = F, Cl or Br) radicals attack. Geometry optimizations and vibrational frequency calculations were performed using three methods: Moller-Plesset second-order
Measurements of the molar heat capacity at constant volume C v for chlorotrifluoromethane (R13) were conducted using an adiabatic method. Temperatures ranged from 95 to 338 K, and pressures were as high as 35 Mpa. Measurements of vapor pressure were made
Thermophysical and thermochemical property data on organic compounds provide vital background information for scientific and engineering communities in both academic and industrial environments. The Thermodynamics Research Center (TRC) has collected an
A bibliography was prepared consisting of references to experimental data for thermophysical properties of mixtures of natural gas components. The bibliography is based on a search of Chemical Abstracts citations from January 1980 to May 1998. The search
This is a database of problems that arise from using a particular ab initio computational method with a particular molecule. It is intended to serve as a guide to prevent people from wasting resources struggling with known problems and to offer solutions
We discuss three computerized databases distributed by the Standard Reference Data (SRD) program of NIST, which are of interest to the natural gas industry.
