Determination of Intermolecular Potential Functions From Macroscopic Measurements
1Institute for Basic Standards, National Bureau of Standards, Washington, D.C.
Abstract:
The second virial, adiabatie Joule-Thomson, viscosity, and diffusion coefficients predicted for a number of potentials are compared with those predicted for the (12, 6) potential. A quantitative picture, as a function of temperature, is obtained of the ability of each property to act as a probe of the potential function. The transport properties are found to be the most sensitive probes, the Joule-Thomson coefficient next, and the second virial coefficient least, the last property being essentially useless in the range 2.0 < T* < 8.0 on the (12, 6) reduced temperature scale.

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...
