AMBER Archive (2008)Subject: AMBER: definition of dihedral in amber
From: Jeffrey (jeffry20072008_at_yahoo.cn)
Dear all,
I am going to write a fortran program to evaluate the torsional energy of each dihedral in a molecule. Could someone tell me how the dihedral is defined as in the following equation:
I noticed that dihedral values were ranged from -PI to PI in CHARMM ff.
Thanks very much for the time.
