Dependence of refractive index on pressure
Show that, in a gas (for which the refractive index is close to 1), the refractive index depends on the pressure as n_r = 1+ K\times p, and find the value of K.
n_r = 1+ K\times p
Clausius-Mossotti equation: \frac{\epsilon_r - 1}{\epsilon_r + 2} = \frac{\rho N_a \alpha}{3M\epsilon_0}
\alpha^'\ = \frac{\alpha}{4\pi \epsilon_0}
n_r = \epsilon_r^{1/2}
I wish I could do organic chemistry...
