Question

Moment of inertia
And classification of molecules on the basis of moment of inertia

Answer 1

Answer:

Classification of molecules on the basis of moment of inertia : The principal axes are ordered such that associated inertia moments decrease, that is, the A-axis has the smallest moment of inertia and other axes are such that IA ≤IB ≤ IC. ... For a linear molecule IA << IB = IC. For most purposes IA can taken to be zero.
