  In this paper, we study the long-time behavior of global solutions to the
Schr\"odinger-Choquard equation $$i\partial_tu+\Delta
u=-(I_\alpha\ast|\cdot|^b|u|^{p})|\cdot|^b|u|^{p-2}u.$$
  Inspired by Murphy, who gave a simple proof of scattering for the non-radial
inhomogeneous NLS, we prove scattering theory below the ground state for the
intercritical case in energy space without radial assumption.
