We have investigated the decays of and with R being the X(4160), Y(3940), Z(3930) and a predicted J = 1 resonances. By using a model in which these states are dynamically generated from the vector-vector interaction, most notably the and states, we predicted five ratios for the production of these states. Some ratios show that the resonance is built from c with or without extra hadronization. In order to offer some extra test for the molecular composition of these states, we have evaluated the invariant mass distributions for the and close to threshold and made predictions for these magnitudes relative to the width for the production of the resonances.
