Assuming that the van der Waals force between two oxygen atoms is described by Lenard Jones potential \[ V(r) = \epsilon_0 \Big( \frac{r_0^{12}}{r^{12}}- \frac{r^6_0}{r^6}\Big)\]
and that \(\epsilon_0=16.4\times10^{15}\) \text{erg}, r_0= 3.88\times10^{-8}\text{cm}\) determine
- the force constant for small oscillations
- the fequency of oscillations for the vibrational motion of a bound pair of He atoms.
- Using the approximate results obtained comote the numerical value of the vibration of oxygen molecule. How do explain the differences between your answer and the experimenl value \(\nu=6.45\times10^{13}\).
