To a first approximation, a diatomic molecule can be represented by a harmonic oscillator. However, we learned that the Morse oscillator provides a better representation of a diatomic molecule.

How do you expect the average bond length of a diatomic molecule would change if the molecule transitions from the ground to any of the excited vibrational levels when: 1) the molecule is represented by the harmonic potential, and 2) the molecule is represented by the Morse potential?
