The moment of inertia of a physical system exhibiting irrotational flow is expressed as a series expansion in terms of the moments of the density distribution. The lowest-order contribution yields a simple relation with the quadrupole moment and is applicable to models of classical and quantum systems. The method is applied in some detail to the special case of the rotational magnetic moment of the hydrogen molecule.
