    • Rigid linear model. The partition function is

    \[ Z(T, V, N)=\frac{1}{N !}\left[\frac{V}{\lambda^{3}(T)}\left(\frac{4 \pi^{3} I k_{B} T}{h^{2}}\right)\right]^{N}\]

    General results for separation of Z into translational (center of mass) and internal degrees of freedom. Term “internal specific heat”.
