This task is devoted to introduce GROMACS notation for force fields. We build the model of hydrazine molecule, introducing lone electron pair as an artificial atom. We set molecular conformations with pairs or by defining dihedral potential. Varying dihedral potentials or pairs we obtain different equilibrium conformations of hydrazine.
