dear Namd/vmd User

I am trying to parametrize my ligand of interest with charmm27 force field
rules. My ligand has nitro benzene group in it. I was wondering which force
field type should i define for nirtogen in nitro group according to
charmm27. Is anyone aware or has faced this issue before. I have checked all
the latest topology files with charm27 force field. but i could not find it.

I would really appreciate your suggestions
