... In the molecular orbitals (MO) approach is to consider the nuclei, without their electrons, at a distance apart which equal to the internuclear equilibrium distance, and to construct MOs around them from linear combination of the atomic orbitals (AO). Electrons are then fed into the MOs in pairs. He ...

... The distance from the origin to the first mass is denoted by r1 , and similarly the distance from the origin to the second mass is r2 . Since we are neglecting the vibrational degrees of freedom both r1 and r2 are constant, and clearly r1 + r2 = re . Since we have chosen the origin of the reference ...
