The problem of the resonance dipole-dipole interaction between two molecules near a spherical semiconductor nanoparticle is considered. It is shown that the presence of the nanoparticle results in the additional interaction between the molecules, which, under certain conditions, can significantly exceed the direct dipole-dipole interaction. This occurs in the case when the ground-state energy of an exciton is in a close resonance with the energies of molecular transitions. The effect of the additional interaction on the probability of intermolecular resonance energy transfer is especially important at large distances between molecules. The matrix elements of the interaction are estimated for nanoparticles of semiconductor materials CuCl and GaAs.
