CCL:G: Calculating interaction energy/bond energy between atoms in mole:Gauss

 Sent to CCL by: "Nikhil  Maroli" [scinikhil[#]]
 Dear all,
 im new to gaussian,
 i wanted to calculate the interaction energy between the atoms in the
 molecules (image :
 I know I can use counterpoise method by making it two fragments ,but how it
 is possible for finding interaction energy between the 1-4,5-28,3-8,11-17.
 how I make fragments?
 Any suggestion will be helpful
