[gmx-users] Lennard jones parameters for ions

[#SUKRITI GUPTA#]

Dear Gromacs users,


I wanted to simulate metal ions in gromacs. For Fe+2, I have lj potential parameters already defined in OPLSAA forcefield, so I wanted to know if I want to add FE+3 in my simulation, then the LJ parameters for it will be different from that of Fe+2 or same?


I thought it will be same because vander waals radii is defined for a element and not ion, hence it will be same for Fe or Fe+2 or Fe+3.


Regards

Sukriti
