Consider a gas of diatomic molecules (moment of inertia I) at an
absolute temperature T. If Eg is a ground-state energy and Eex is
the energy of an excited state, then the Maxwell-Boltzmann
distribution predicts that the ratio of the numbers of molecules in
the two states is nexng=e−(Eex−Eg)/kT. The ratio of the number of
molecules in the lth rotational energy level to the number
of molecules in the ground-state (l=0) rotational level is
nln0=(2l+1)e−l(l+1)ℏ2/2IkT. The moment of inertia of...
