A rigid rotor has two particles of mass m attached to the ends of a massless rigid rod of length a. The rotor is free to rotate in three dimensions about the center of mass. This is a model for the rotational motion of a homonuclear diatomic molecule, a molecule with two identical nuclei. (An example is 16O2.) (a) By expressing the Hamiltonian in terms of the orbital angular momentum, show that the allowed energies of this rigid rotor are...
