                         faithfully for the symmetry properties of the systems, preserving 
                         at the same time a compact analytical form. To this aim, the 
                         choice of a proper set of coordinates is a necessary precondition. 
                         Here we illustrate a description in terms of hyperspherical 
                         coordinates and the expansion of the intermolecular interaction 
                         energy in terms of hypersherical harmonics, as a general method 
                         for building potential energy surfaces suitable for molecular 
                         dynamics simulations of van der Waals aggregates. Examples for the
