Abstract. Available experimental data on decay rates for $B \rightarrow \psi K$, and decay rates and transversity amplitudes for $B \rightarrow \psi K^*$ are used to investigate nonfactorization contributions in these decays using five different theoretical models for the formfactors. Using the knowledge on nonfactorization so gained, we study the processes $B_s \rightarrow \psi (\eta, \eta')$, $B_s \rightarrow \psi \phi$ and $B \rightarrow \psi(2S) K^*$. We find that present experimental data for the last two processes are consistent with the predictions of most of the models considered.
