$\gamma =1+\frac{2}{\mathrm{f}}$
$f=6$, Triatomic rigid gas
$\mathrm{f}=7$, Diatomic non-rigid gas
$f=5$, Diatomic rigid gas
$\mathrm{f}=3$, monoatomic rigid gas
$\gamma =1+\frac{2}{6}=\frac{4}{3}$ (Triatomic)
$\gamma =1+\frac{2}{7}=\frac{9}{7}($ Diatomic, non-rigid $)$
$\gamma =1+\frac{2}{5}=\frac{7}{5}($ Diatomic, rigid $)$
$\gamma =1+\frac{2}{3}=\frac{5}{3}($ Monoatomic, rigid $)$
