Question:

Calculate the reduced mass for the H35Cl and H37Cl molecules and the fractional difference ??μ/μ. Show that the mixture of isotopes in HCl leads to a fractional difference in the frequency of a transition from one rotational state to another given by ??f/f = ??μ/μ. Compute ??f/f and compare your result withFigure.
