Dear Sirs :
        It is well-known that benzene dimer has two possible geometries.

        One of these is T-shaped where one benzene molecule is
perpendicular to the othe   other one.
The other is the so-called shifted parallel one.
         Is there something known about the dimers of thiophene, furan
and pyrrole
         molecules? Any references will be greatly appreciated.
         Thanks in
anticipation!....................................students of Professor
