4. In classical mechanics the rotational energy of a rigid body is $\qquad E = \frac{1}{2} \left( \frac{J_x^2}{I_x} + \frac{J_y^2}{I_y} + \frac{J_z^2}{I_z} \right)$, \qquad (5) where the $I_i$ are the moments of inertia about the body's three principal axes and $\vec{J}$ is the body's angular-momentum vector. In case of quantum system, we can write the Hamiltonian and the (total) angular momentum operators as $\qquad H = \frac{\hbar}{2} \left( \frac{J_x^2}{I_x} + \frac{J_y^2}{I_y} + \frac{J_z^2}{I_z} \right)$. \qquad (6) Show that for diatomic molecules whose body symmetric around z axis ($I_x \equiv I_z = I_y$), we have eigenvalues of energy: $\qquad E_{jm_j} = \frac{\hbar}{2} \left\{ \frac{j(j+1)}{I} + m_j^2 \left( \frac{1}{I_z} - \frac{1}{I} \right) \right\}$. \qquad (7) The transition of energy ($E_p$) for the rotational diatomic is given by $\qquad E_p = \pm (E_j - E_{j-1}) = \pm j \frac{\hbar^2}{I}$. \qquad (8) Explain why CO molecule can emit or absorb photon due to this transition energy meanwhile O$_2$ cannot ?
