molecular mechanics evaluates a parametrized potential of atomic positions, with terms such as bond stretching, angle bending, torsion and nonbonded interactions. electrons are represented implicitly through the fitted force field, rather than by electronic orbitals, a density or an electronic wavefunction. This example is different from both preceding electronic methods.
