The challenges with the molecular model of multiquark systems are identification hadronic molecules and interaction between two color neutral hadrons. We study di-hadronic proposed potential as s-wave one boson exchange along Screen Yukawa-like potential, arrived proposal that within molecule hadrons experience dipole-like interaction. present is continuation our previous \cite{arxiv-Rathaud-pe...
