Hi,
I read in Amber10 manual that "charges that are not centered on atoms,
but are off-center (as for lone-pairs or "extra points") can be included in
the force field."
I was wondering if you could give me an idea of how to add two extra points
around the C atom in CN- ion. In polarizable force fields it adds
"Epol = −2Σμi ·Eio"
where the dipole moment is induced dipole moment.
I was trying to add a similar term with a 'permanent' dipole moment around
C atom in a simulation of CN- in H2O.
Thank You
