Rotational chirality is a phenomenon associated with spontaneous symmetry breaking by unidirectionally spinning molecules into so-called rotational-cluster states [1,2]. These states are characterized by strong centrifugal forces pulling the symmetry-equivalent atoms in the molecule into different directions, thus breaking permutation symmetry. Here, we consider the effects of nuclear-spin hyperfine mixing in rotationally chiral states. For the H2S molecule we demonstrated, through comprehensive variational calculations, strong ortho-para state mixing in rotational cluster states leading to the generation of spin polarization and magnetization.
