[Pw_forum] H-bonding in DFT

[ZARA NBSH]

Dear all

​I would like to study the interaction between two organic molecules
(contains C, H and O atoms).
It seems that hydrogen-bonding between H and O atoms of different molecules
play an important role.

My question is that what is the best method to study this system?
Could usual DFT (GGA for example blyp PP) have a correct prediction of this
system?

I really appreciate your help in advance.
