Nuclear fission produces fragments whose spins are coupled to each other as well as to the relative fragment motion due to angular momentum conservation. Statistical ensembles of such spins can readily be obtained by either direct microcanonical sampling or by sampling of the associated normal modes of rotation. The spin-spin opening angle distribution is illustrated for both 3D and 2D spin scenarios and it is demonstrated how recent calculations with various models can be well reproduced by the statistical results under different assumptions about the scission geometry.
