If the diatomic molecule is non-rigid, then its molar specific heat capacity at constant volume is
If the diatomic molecule is non-rigid, then its molar specific heat capacity at constant volume is
Show Hint
For rigid diatomic molecules, $f=5$ and $C_v = \frac{5}{2}R$. Vibration only counts for non-rigid molecules.
