Abstract: Exclusive non-leptonic two-body decays are discussed on the basis of a generalized factorization approach which also includes non-factorizeable contributions. Numerous decay processes can be described satisfactorily. The success of the method makes possible the determination of decay constants from non-leptonic decays. In particular, we obtain fDs=(234±25)MeV and fDs*=(271±33)MeV. The observed constructive and destructive interference pattern in charged B and D decays, respectively, can be understood in terms of the different αs-values governing the interaction among the quarks. The running of αs is also the cause of the observed strong increase of the amplitude of lowest isospin when going to low-energy transitions.
