Abstract

The orientation of water molecules in the neighborhood of a liquid-liquid interface in detail was analyzed. This type of orientation became common to characterize by the angle between the interface normal an some characteristic molecular vectors describing the spatial orientation of the individual molecules, such as the molecular dipole vector or the vector connecting the nuclei of the two H atoms. This paper shows that the fairly common practice of plotting the statistical distribution of such vector angles as well as their average values as a function of distance from the interface have pitfalls that can be avoided by applying simple concepts of multivariate statistics.
