Highly Excited Vibrational States and Chemical Reactivity
The movement of nuclei on the potential energy surface created by electrons has a fundamental role to play in the “becoming” of matter in the animate and inanimate world. In fact, every chemical reaction happens just because, at a given instant and due to particular circumstances, a certain nucleus (or group of nuclei) may receive sufficient energy to escape from the potential well in which it exists, vibrating around an equilibrium position. It may then leave the rest of the molecule or begin to oscillate around a new equilibrium position.
