Similar to exercise 1, find the vibrational frequency of the molecule by applying harmonic potential model. Given the reduced mass to be $\mu=\frac{m_1m_2}{m_1+m_2}$
Similar to exercise 1, find the vibrational frequency of the molecule by applying harmonic potential model.
5. Find the correction term to the harmonic potential expressed in (3) that defines the anharmonicity of the potential energy U(r) at a finite distance away from $r_0$.
## Exercise 3: Vibrational spectra
Consider the frequency of oscillation of a CO molecule to be $6.4\cdot10^{13}$ Hz.
1. Calculate the reduced mass, $\mu$, for the CO (The atomic mass of C ≡ 12 amu, O ≡ 15.9 amu)
2. Find the spring constant, k, corresponding to the oscillation of CO molecule.
3. Calculate the change in vibrational energy, $\Delta E$, that can lead to an electron transition.
