Query: Interaction energies of monosubstituted benzene dimers via nonlocal
  density functional theory   We present density-functional calculations for the interaction energy of
monosubstituted benzene dimers. Our approach utilizes a recently developed
fully nonlocal correlation energy functional, which has been applied to the
pure benzene dimer and several other systems with promising results. The
interaction energy as a function of monomer distance was calculated for four
different substituents in a sandwich and two T-shaped configurations. In
addition, we considered two methods for dealing with exchange, namely using the
revPBE generalized gradient functional as well as full Hartree-Fock. Our
results are compared with other methods, such as Moller-Plesset and
coupled-cluster calculations, thereby establishing the usefulness of our
approach. Since our density-functional based method is considerably faster than
other standard methods, it provides a computational inexpensive alternative,
which is of particular interest for larger systems where standard calculations
are too expensive or infeasible.
