2.27 The oscillation of the atoms around their equilibrium positions in the molecule HI can be modelled as a harmonic oscillator of mass m my (the iodine atom is almost stationary) and force constant k = 313.8 Nm-. Evaluate the separation of the energy levels and predict the wavelength of the light needed to induce a transition between neighbouring levels. 2.28 What is the relative probability of finding the HI molecule with its bond length 10 per cent greater than its equilibrium value (161 pm) when it is in (a) the v = Ostate, (b) the u = 4 state? Use the information in Problem 2.27.
