✦ Synopsis

The surface energy, the surface free energy and the surface entropy of liquid \cater are cakulated from the decrease in the number of hydrogen bonds in the surface layer, estimated on the basis of a simplified wafer structure scheme. In the calculations of the free energy density function only the hydrogen-bond interactions between molecules are taken into consideration. The resulting surface free energy of water is ==43 mNlm at 25°C. The calculated temperature dependence is consistent with that observed_

A self-consistent treatment of reaction field effects on isotropic (14)N hyperfine coupling constants of nitroxide spin labels in mixtures of polar and apolar solvents is given based on the Onsager approach. It is shown that this works reasonably well for mixtures of water or methanol with dioxane,
