Decay modes: of psi, psi', eta/sub c/ are examined within a model of Okubo-Zweig-Iizuka (OZI) -rule violation based on the S-matrix topological expansion (SMTE). The model provides an appropriate language for discussing general features of the OZI rule and successfully predicts the order of magnitude of the decrease in widths between phi and psi. Because of the relatively strong mixing of eta and eta' with eta/sub c/ necessitated by the SMTE, these mesons play a prominent role in psi, psi' decays. We readily explain the ''large'' psi' ..-->.. etapsi, psi ..-->.. eta'..gamma.., psi ..-->.. eta..gamma.. rates and predict several more channels involving eta and eta' into which the new particles should frequently decay. We describe why there is no general concept of double-OZI-forbidden processes and successfully correlate the role the epsilon meson plays in such reactions as psi' ..-->.. psiepsilon, psi ..-->.. epsilon..omega.., psi ..-->.. epsilonphi. The differences between psi and psi' decays expected because of the radially excited nature of the psi' are touched upon, and it is speculated that GAMMA(eta/sub c/) approx. = GAMMA (phi ..-->.. rho..pi..). Comparison is made with other models of OZI suppression. (AIP)
