a) For a heteronuclear diatomic molecule, draw an energy level diagram showing the four lowest rotational energy levels. Indicate the energy of each level in terms of B. Indicate all possible light absorption transitions. b) Draw a spectrum (absorbance vs. frequency) corresponding to the transitions you have shown in part a). Indicate which transitions in the energy level diagram correspond to which peaks in the spectrum.
