Question:
The number of rotational degrees of freedom of a diatomic molecule is:
The number of rotational degrees of freedom of a diatomic molecule is:
Show Hint
For linear molecules like diatomic gases, only two axes of rotation are effective — those perpendicular to the bond axis.

Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
A diatomic molecule can rotate about two axes perpendicular to the bond joining the atoms. It cannot rotate about the bond axis due to negligible moment of inertia.
Thus, rotational degrees of freedom = 2.
Thus, rotational degrees of freedom = 2.
