Thanks for your
I am not mixing up the parameter here.
What i am trying to do here
In order to reproduce the dipole moments of the CO, I have to
follow up the specific charges and non-bonded interaction values specified in
literature in CHARMM format ( For C atom, charge -0.75, ϵ=0.0262
& σ = 3.83) ( For O atom, charge -0.85, ϵ=0.0262 & σ =
Could you tell how it can be done? If i cant use them in
gromos43a1 ff, possible to use in charmm27 provided by gromacs package? or it
does need any conversion to use in gromacs-charmm27 ff?
Thanks for you answer.

You don't. You can't use the parameters of one force field (CHARMM) within
another (Gromos96 43A1). It is fundamentally unsound to try to mix and match
