The Born-Oppenheimer approximation is a special form of this approximation, which states that a particle initially in the nth eigenstate of an initial Hamiltonian will evolve into the nth eigenstate of a final Hamiltonian, if the transition from the initial Hamiltonian to the final Hamiltonian is slow.
