Abstract
One important object of molecular quantum mechanics is the calculation of the stationary state energies of molecular systems as functions of the geometrical configuration of their nuclei. By finding the energy minima one can predict the equilibrium geometric form of molecules, including internuclear distances and bond angles. The procedure implies the use of the Born-Oppenheimer approximation which is known to be excellent for the ground electronic state of most molecules.
