Many diatomic (two-atom) molecules are bound together by covalent bonds that are much stronger than the van der Waals interaction. Examples include H2, O2, and N2. Experiments show that for many such molecules, the interaction can be described by a force of the form F, = A –26(r–Ro) -b(r- where A and b are positive constant, r is the center-to-center separation of the atoms, and Ro is the equilibrium separation. For the hydrogen molecule (H2), A = 2.97 × 10-8 N, b = 1.95 x 1010 m-1, Ro = 7.4 × 10-1" m. Find the force constants for small oscillations around equilibrium. (Hint: Use the expansion for e*.)
