How does bond energy relate to potential energy?

WebAt r 0, the ions are more stable (have a lower potential energy) than they are at an infinite internuclear distance. When oppositely charged ions are brought together from r = ∞ to r = r 0, the energy of the system is lowered (energy is released). Because of the low potential energy at r 0, energy must be added to the system to separate the ions. WebSolution of the electronic Schr˜odinger equation gives the energy as a func-tion of internuclear distance E elec(R). This plays the role of a potential energy function for motion of the nuclei V(R), as sketched in Fig. 2.
