  We study the interesting problem of interaction and identification of the
hadronic molecules which seem to be deuteron-like structure. In particular, we
propose a binding mechanism in which One Boson Exchange Potential plus Yukawa
screen-like potential is applied in their relative s-wave state. We propose the
dipole-like interaction between two color neutral states to form a hadronic
molecule. For the identification of the hadronic molecules, the Weinberg's
compositeness theorem is used to distinguish the molecule from confined
(elementary) state. The present formalism predict some di-hadronic molecular
states, involving quarks (s, c, b or $\overline{s}$, $\overline{c}$,
$\overline{b}$) as a constituents, namely, $pn$, $K\overline{K}$, $\rho
\overline{\rho}$, $K^{*}\overline{K^{*}}$,
$D\overline{D^{*}}$($\overline{D}D^{*}$), $D^{*}\overline{D^{*}}$,
$B\overline{B^{*}}$, $B^{*}\overline{B^{*}}$,
  $D^{*\pm}\overline{D_{1}^{0}}$, $ D^{0}\overline{K^{\pm}}$,
$D^{*0}\overline{K^{\pm}}$, with their possible quantum numbers.
