            Why Molecules at Surfaces are Compressed

It is conventional wisdom that molecules at surfaces are much like
molecules in the bulk, e.g. it generally is assumed that gas molecules
adsorbed at a surface have a density that is the two-dimensional
equivalent of the normal liquid density.  In this presentation it will
be shown that this assumption is wrong and that under most circumstances
molecules at surfaces and interfaces are compressed, i.e. their
densities are higher than in the bulk and they experience strong
repulsive interactions with their neighbors.
