 Dear RAM,

The first thing is to define the physical base of the so-called C-H -piand pi-pi interactions.

 Once this is done, the rest is easier.
 Best regards,

 Dear All,
          How can we separate CH-pi and pi-pi interaction into strong, moderate
 and weak based on the bond distance and bond angles (geometrical parameters) in
 pure organic substances? Whether is there any reference available for this?
         On what basis this kind of interactions (CH-pi and pi-pi) is separated,
 and I would like to know how this CH-pi and pi-pi interactions can be classified
 as strong, moderate and weak.Please help me in this regards.
 Thanks in advance
 With Regards,
 RAAM>
