1. The problem statement, all variables and given/known data Predict the wavenumber (cm-1) position of infrared absorption due to fundamental vibration from v=0 to v=1 and 2nd overtone from v=0 to v=3. For a harmonic occilator whose frequency=8.00x1013 s. 2. Relevant equations Energy expression for harmonic oscilator: Ev= (v+1/2)hv v=1, 2, 3.... 3. The attempt at a solution I am not at all sure of my answers, but this is what I did: Fundamental Vibration: E0= (0+1/2)*6.626x10-34*8.00x1013 s = 2.504 x 10-20 E1= (1+1/2)*6.626x10-34*8.00x1013 s = 7.9512 x 10-20 E3= (3+1/2)*6.626x10-34*8.00x1013 s = 1.85528 x 10-19 Then I found difference between energies: E1-E0=5.4472*10-20 and E3-E0=1.60488*10-19 I have no clue how to find the infrared absorption from this. Please help me ASAP. Thanks.
