The moment of inertia for an axis through the center of mass of a diatomic molecule calculated from the wavelength emitted in an l = 19 -> l = 18 transition is different from the moment of inertia calculated from the wavelength of the photon emitted in an l = 1 -> l = 0 transition. Explain this difference. Which transition corresponds to the larger moment of inertia?
