Show Abstract
The kinetic theory of gases in the limit of zero density and that of moderately dense gases is used to generate accurate tables of the viscosity and thermal conductivity of the pure monatomic gases for zero density and for a pressure of 0.101325 MPa. The theoretically‐based tables cover the temperature range from the normal boiling point of the relevant gas up to 5000 K. The associated uncertainties of the proposed data are detailed in the paper. A comparison of the correlated data with experimental results and some other recent correlations is given.

Show Abstract
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 carried out. The review covers the period from 1983 through the end of 1988 and represents a continuation of earlier critical reviews up to 1982. Data tables containing the selected experimental Stark broadening parameters are presented with estimated accuracies. Guidelines for the accuracy estimates have been done developed during the previous reviews and are summarized. The data are arranged according to elements and spectra, and these are presented in alphabetical and numerical order, respectively. Comparisons with comprehensive calculations based either on the semiclassical theory, or—for multiply ionized atoms—on the modified semiempirical approximation, are made whenever possible, since the comparison with theory has often been a principal motivation for the experiments.

Show Abstract
New information on the experimentally determined vibrational and electronic energy levels of approximately 500 neutral and ionic transient molecules possessing from 3 to 16 atoms has been evaluated and added to the previously established database for these species. There has been selective extension of the compilation to somewhat less reactive species such as HNCO, HCNO, H2O2, and cis‐ and trans‐HONO, as well as to many transient molecules which include atoms beyond the third row of the Periodic Table. Electronic spectral data are also given for a number of transient molecules which possess more than six atoms. Radiative life‐times and the principal rotational constants are included. Observations in the gas phase, in molecular beams, and in rare‐gas and nitrogen matrices are evaluated. The types of measurement surveyed include conventional and laser‐based absorption and emission techniques, laser absorption with mass analysis, and photoelectron spectroscopy.

Show Abstract
The thermodynamic and thermophysical properties of eight primary amines, methanamine, ethanamine, 1‐ and 2‐propanamine, benzenamine, and 2‐, 3‐, and 4‐methylbenzenamine have been evaluated. Recommended values are given for the following properties: normal boiling, freezing, and triple‐point temperatures, critical constants, thermodynamic properties in the solid and liquid phases, vapor pressure, enthalpy of vaporization, density, second virial coefficients, and enthalpy of combustion. Ideal gas thermodynamic properties have been calculated by statistical mechanical methods.
