(a) Draw a rough schematic of the series of resonances corresponding to a vibrational transition for a diatomic. Label the P and R branches, explain what the difference is between them, and indicate what the spacing is between the resonance lines. (b) What is the main information about a diatomic molecule that one can obtain from vibrational and rotational transition frequencies (assuming that the reduced mass is known)?
