The dynamics of the  J  PC  = 0 -+ ,0 ++ , and 2 ++  resonance contributions to the decay $ J/\psi {\rm{ }} \to {\rm{ }}\gamma X\left( {{J^P}} \right) \to {\rm{ }}\gamma \phi \phi $ is analysed using the data obtained by BESIII collaboration. The effective coupling constants parameterising invariant amplitudes of the transitions $ J/\psi {\rm{ }} \to {\rm{ }}\gamma X\left( {{J^{PC}}} \right) $ and $ X\left( {{J^P}} \right) \to {\rm{ }}\phi \phi $ and masses $ X\left( {{J^P}} \right) $ of found from the fits are used to plot $ \phi \phi $ the mass spectrum of each  J  PC  component.
