Equations for T V V and T T P couplings are derived from dual amplitudes for the processes P + V + P + V and P + T+ P + P. The couplings are expressed in terms of other mesonic couplings, known from experiment. With the aid of these couplings we calculate the decay rates o f A,-WTP, f -p.rr.rr, K * * i K*mr and the electromagnetic decays A,, f i V y , and y y . The calculated rates for A,+on?r and f+pn.rr are smaller (by about a factor of 4) than the average experimental data. This discrepancy is analyzed in terms of a consistent picture for all the decays studied in this paper.
