The decay process psi' ..-->.. psieta is regarded as an Okubo-Zweig-Iizuka (OZI) rule violating transition since we assume no a priori admixture of cc-bar quarks in eta. Unitarity corrections to the OZI rule are computed within the context of dual model and found to be roughly two orders of magnitude larger than in the case of psi' ..-->.. rho..pi... Using the vector-dominance model the radiative decays psi ..-->.. eta..gamma.. and psi ..-->.. eta'..gamma.. are investigated. Dynamical violations of SU(3) introduced by the mass difference between charmed mesons in the same SU(3) multiplet are adequate to explain the experimentally observed ratio GAMMA (psi ..-->.. eta..gamma..)/GAMMA (psi ..-->.. eta'..gamma..).
