How to get Moment of inertia of diatomic molecule?

The total moment of inertia is the sum of the moments of inertia of the mass elements in the body. And moment of inertia of mass element is mass of particle times square of the radius (distance from center of mass). So to get total moment of inertia we add moment of inertia for both mass element (m1 and m2).
