Molecules can rotate as rigid bodies. The spectrum of a quantum rotor is given by the eigenvalues of the Hamiltonian L2 = H and (H) = E = J(J+1)h² 2M, R 21 where M, is the reduced mass of the nuclei and Ro their equilibrium separation. There exists in nature a particle known as the muon. It is just a heavy electron with a mass m, = 207me. It decays in 10-º seconds. Suppose there exists a molecule analogous to H, (two protons + 1 electron), but with the electron replaced by a muon:
