The formulas for the Raman intensities of fundamental and n-th overtones were investigated theoretically, starting from the Kramers-Heisenberg dispersion formula and referring to a diatomic molecule in a harmonic potential approximation. The derived formulas were then applied to fifteen overtone bands of iodine, which have been observed in gas, and to the exciting frequency dependence of the fundamental and the first overtone intensities of iodine in a CHCl3 solution. It was shown that the formulas quantitatively explain the trend of the observed data well.
