Question

For a diatomic molecule, the number
of degrees of freedom is :​

Answer 1

Explanation:

The molecules will have two independent rotational motions. If the molecule lies on the x-axis, then one rotational motion is about y-axis (in the x-z plane) and the other one is about z-axis (in the x-y plane). Therefore, a diatomic molecule has 5 degrees of freedom- 3 translational and 2 translationa
