A critical review of the available experimental data on Stark widths and shifts for spectral lines of non-hydrogenic neutral atoms and positive ions has been
This review contains selected values of thermodynamic quantities for the aqueous ionization reactions of 63 buffers, many of which are used in biological
A new formulation has been developed to represent the vapor pressure of heavy water (D 20) from its triple point to its critical point. This work takes
Experimental data on the enthalpies of formation of chloromethanes, chloroethynes, chloroethenes, and chloroethanes are critically reviewed. Enthalpy of
The structural, spectroscopic, and thermodynamic properties of ten organic molecules in the gas phase, including three peroxides and four carboxylic acids, have
The limited electron collision cross-section and transport-coefficient data for the plasma processing gas perfluorocyclobutane (c-C 4F 8) are synthesized
This paper gives the 1998 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on
A new formulation is presented for the thermodynamic properties of refrigerant 143a (1,1,1-trifluoroethane, CH 3-CF 3) based upon available experimental data

A correlation for estimating the vapor pressure of normal alkanes from methane through n-hexatriacontane and isomers of butane to nonane is reported. This work
Low-energy electron collision data for the plasma processing gas CF 3I are sparse. Limited cross section data are available only for total and differential
Sulfur hexafluoride (SF 6) is commonly used as a gaseous dielectric and as a plasma etching gas. In this work, the state of knowledge on electron-interaction
Twenty-eight (28) crystalline and aqueous chromium species from the NBS Thermodynamic Tables were selected based upon their possible importance to environmental
