Homework Help: Quantum Harmonic Oscillator

  1. Nov 2, 2011 #1
    1. The problem statement, all variables and given/known data

    "Vibrational spectroscopic studies of HCl show that the radiation absorbed in a transition has frequency 8.63*10^13 Hz. Calculate the vibrational frequency of the molecule in this transition."

    2. Relevant equations


    3. The attempt at a solution

    I know I'm supposed to calculate the energy absorbed in the transition first, so:
    E = hv
    E = (6.626*10^-34)(8.63*10^13)
    E = 5.72*10^-20 J

    From here, I guess I'll have to use the equation: E_n=(n+1/2)hv, but what n value(s) do I use? Kind of confused here.
