By examining two different isotopes one can determine specific features about the molecule and its absorption spectrum.( Spectroscopy is a very useful tool for investigating the properties (e.g. structures) of molecules.)
Calculate the vibrational level energies in units of the Planck constant h for H35Cl and H37Cl where ˜ν35 = 2885.64 cm-1 and ˜ν37 = 2883.456 cm-1, What is the probability of populating the first excited vibrational state (n = 1) at 298 K? Does isotopic substitution affect the probability? Would the intensity of absorption peaks be affected by isotopic substitution? If yes, which isotope has a greater intensity?
