We study mass spectra of a meson-meson system involving two light and two heavy quarks on an anisotropic lattice. The heavy quarks are treated in the static approximation. The dependence of the spectrum on the relative distance of the heavy quarks is extracted from the lattice simulation using the maximum entropy method (MEM). A correlation matrix of meson-meson operators emphasizing quark and gluon exchange degrees of freedom is employed in an attempt to learn about aspects of mechanisms of hadronic interaction.
