The infrared absorption spectrum of 1H35Cl has its strongest band at 8.65 × 1013 Hz, which corresponds to the excitation from its ground vibrational state to the first excited vibrational state.
a) Use the harmonic oscillator approximation to calculate the force constant of the bond in this molecule.
b). Find the corresponding zero-point energy.
c). Predict the photon frequency of the strongest infrared band of 2H35Cl. Use computer software to draw the wave functions of the first four eigenstates (using the harmonic oscillator approximation).
