2.The potential energy of a diatomic molecule is, where both A and b are
positive constants and r is the distance between the two atoms.
申論題內容
(c) If x is the difference between r and R0and x is much smaller than R0, use Taylor's expansion to show that F is proportional to x and derive the force constant k in terms of A and b.
