ABSTRACT.  In this work, we give an improvement of the adiabatic approximation of the
resolvent and wave operators for diatomic molecules obtained by
Klein-Martinez-Wang. Following Mourre's commutator method, we use a new
kind of escape function. In the same way, we deal with matricial
Schroedinger operators and the Dirac operator with scalar electric
potential.
