Abstract. The aim of this paper is to justify the physical intuition that the quantum scattering of a diatomic molecule is well approached by a classical 2-body system when the nuclei's mass are large. To this end, we compute the action of an elactic scattering operator on quantum observable, microlocalized by coherent states. An adiabatic operator makes the connection between the quantum scattering and the classical one.
