Diatomic Molecules. (16 points) Consider a gas of N noninter acting diatomic molecules, each having a dielectric dipole moment it, placed in an external electric eld of strength E. The energy of such a molecule con- sists of the kinetic energy of translation and rotation as well as the potential energy of orientation in the applied electric eld: 2 2 2 P :p_+p_9+ E 6 2m 21 21311126 \" COS where I is the moment of inertia of the molecule. Assume that the system is classical and that IMEI
