Hello
How can a monochromatic light induce a transition ( absorption ) between two energy levels whose energy difference doesn't match the frequency of the incident light ?? A treatment using time dependent perturbation theory shows that the transition will occur even when the incident radiation frequency and hence the energy of its photons is less than the difference between the two levels !
