Vibrations of molecules can be approximated by a harmonic oscillator only near the mini- mum of the binding potential curve, i.e., for small amplitudes for vibrations. Much better description is provided by the Morse potential 2 1 -h?w² ( n+ 4De En = hw ( n + A) Consider the 39K 35C1 molecule. In the far infrared spectrum, it has an intense line at 278.0 cm-1. Assume that it is an ideal quantum harmonic oscillator and estimate the period of vibration of the molecule. B) Now consider that 39K 35C1 molecule is described with a Morse potential with De 34843.15 cm-1 (this value comes from an experimental fit from the literature). If the excitation from the vibrational ground state to the first excited state is 278.0 cm-1, how much would the period of vibration change? How much would the energy transition between the first and second excited vibrational level differ from 278.0 cm-1?
