Estimate the classical rotational period in seconds of CO molecule in its J=1 state using the classical equation of motion for rotation, d/dtV(t)=L/I where I is the moment of inertia and L is the angular momentum. One period is the time it takes for theta to increase to 2pi.
Equate the square of the classical angular momentum to the quantum eigenvalue L^2.
