In this article, we calculate the contributions of the vacuum condensates up to dimension 10 in the operator product expansion, and study the,,,,,molecular states with the QCD sum rules. In the calculations, we use the formulato determine the energy scales of the QCD spectral densities. The numerical results favor assigning theandto the,ormolecular states, theto themolecular state, theto themolecular state, and they disfavor assigning theto the () molecular state. The present predictions can be confronted with the experimental data in the future.
