Question

A diatomic molecule has atoms of masses m1 and m2. The potential energy of the molecule for the interatomic separation r is given by V(r) = -A + B(r - ro)^2, where ro is the equilibrium separation, and A and B are positive constants. The atoms are compressed towards each other from their equilibrium positions and released. What is the vibrational frequency of the molecule? A. 1/2π(2B(m1 + m2)/m1m2)^0.5 B. 1/16π(2B(m1 + m2)/m1m2)^0.5 C. 1/8π(2B(m1 + m2)/m1m2)^0.5 D. 1/4π(2B(m1 + m2)/m1m2)^0.5
