Predicting spectroscopic transition positions

  1. Sep 28, 2008 #1
    The harmonic oscillator is a model for the vibrating diatomic molecule. The energy expression for this model is given by:

    Ev = (v+1/2) hν v = 0, 1, 2, 3,… (ν = oscillator frequency)

    Use this expression to predict the wavenumber (cm-1) position of the infrared absorption due to the fundamental vibration (v = 0 --> v = 1) and the second overtone (v = 0 --> v = 3), for an harmonic oscillator of frequency ν = 8.00 x 1013 s, which is typical for a diatomic molecule.

    If anyone can guide me as to what the question is asking for, how to setup the question and solve it I will really appreciate it.

    I think this question has to do with gaps between energy level.
