WebFor diatomic molecules like N 2 and O 2, you include two degrees of rotational freedom, so f=5 and γ = 1.4 . Since almost all of the atmosphere is nitrogen and oxygen, ... For polyatomic molecules, there are three degrees of rotational freedom and this along with the three translational degrees of freedom would give γ = 4/3. But in the ... WebThe diatomic molecule can rotate about any axis at right angles to its own axis. Hence it has two degrees of freedom of rotational motion in addition to three degrees of freedom of translational motion along the three axes. So, a diatomic molecule has five degrees of freedom as shown in figure. Examples: molecules of O 2, N 2, CO, Cl 2, etc.
