Question 1

The moment of inertia of a CO molecule is 1.46 × 10⁻⁴⁶ kg ⋅ m². What is the wavelength of the photon emitted if a rotational transition occurs from the J = 3 to the J = 2 state?

Question 2

The rotation spectrum of the HCl molecule has been observed in the far infrared, around 50 × 10⁻⁶ m. The spacing between successive lines in the spectrum corresponds to radiation of wavelength equal to 5 microns (1 μm = 10⁻⁶ m). Determine the frequency of the photon associated with this transition.
