The ab initio determination of the leading long-range term of pairwise additive dispersive interactions, based on the independent analysis of the response properties of the interacting objects, will be considered in the case where these are part of a periodic system.

Applications on the adsorption of molecule (A) on slab [1] and nanotube [2] (B) will be presented, and comparison with CRYSCOR results for the whole system (A+B) in the dissociative part of the potential energy will be given.
