C 9/23/99 Added improper rotation matrices and matrices of dipole-dipole 
C         interactions     
c 7/25/08 Commented out; not needed when cumulants used
C Interactions of pseudo-dipoles generated by loc-el interactions.
      double precision dip,dipderg,dipderx
      common /dipint/ dip(4,maxconts,maxres),dipderg(4,maxconts,maxres),
     &  dipderx(3,5,4,maxconts,maxres)
