Hi Amber users
Nonbond interactions (vdw, and electrostatics) in parm99 or gaff are the same.
In Gaff paper it says concerning LJ (vdw), that:
The van der Waals parameters of GAFF are as same as those used
by the Amber parm94 or parm99 force fields. There is only one set
of parameters (the internuclear separation of the ij pair at the
potential minimum, r*ij, and the potential well, ij) for each element
except hydrogen.
What does "except hydrogen" mean? do they have or not corresponding vdw in
there?
Thanks in advance
