However, the opposite behavior is observed for the CG model, with the diffusion coefficients for the out-of-plane and in-plane axes respectively overestimated and underestimated compared with the FG model. The higher rate of reorientation of the out-of-plane axis in the CG model is as expected from the general increase of mobility upon integrating out degrees of freedom by coarse-graining. On the other hand, the lower rotational rate of the in-plane axis in the CG model can be explained by the absence of the reorientational mode present in the FG model that involves rotation around the out-of-plane axis, due to the symmetry of the uniaxial CG particles.
