Problem 10-58a: The equilibrium separation between the nuclei of the nitrogen molecule (N2) is 0.190 nm and the mass of each nitrogen nucleus is 14.0 u, where u = 1.66E-27 kg. For rotational energies, the total energy is due to rotational kinetic energy. Approximate the nitrogen molecule as a rigid dumbbell of two equal point masses and calculate the moment of inertia about its center of mass. Calculate the rotational energy levels for l = 1 and l = 2 using the relation El = l(l+1)hbar2/(2/I). Anyone have any suggestions on how to tackle this problem?
