= Rotational energy
{title2=$E_J=\hbar^2J(J+1)/(2I)$}

For a <linear rigid rotor> with <moment of inertia> $I$, the <energy eigenvalue> at <angular momentum quantum number> $J$ is $\hbar^2J(J+1)/(2I)$. Each level has <statistical weight> $2J+1$ before additional symmetry or nuclear-<spin> restrictions.
