Subject: AMBER: Azobenzene: dihedral angle CCNN force field parameter

From: Chih-Ying Lin (

I found that the dihedral CCNN force field for the azobenzene are not quite right.
0 3.14 3.0 :1_at_CAH :1_at_CAM :1_at_NAK :1_at_NAL (9,11,12,13)

With this set of parameters, the two phenl rings can rotate freely.
Any one have idea for this?
