  It is known that the ground states of organic conductors have a diversity
reflecting the spatial arrangement of the constituent molecules within the unit
cell. A systematic theoretical search for the unifying view behind such
possible ground states has been made based on the Hartree-Fock mean field
approximation not only to the on-site but also to intersite Coulomb
interactions with special emphasis on the families of typical organic
conductors (TMTCF)$_2X$ and (ET)$_2X$.
