The object of molecular mechanics is to predict the energy associated with a given conformation of a molecule. However, molecular mechanics energies have no meaning as absolute quantities. Only differences in energy between two or more conformations have meaning. A simple molecular mechanics energy equation is given by:

Energy =

  • Stretching Energy +
  • Bending Energy +
  • Torsion Energy +
  • Non-Bonded Interaction Energy
