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.
