Dominant diagonal terms of diffusion matrices (a) ${\stackrel{\rightharpoonup }{\stackrel{\rightharpoonup }{D}}}_{{kk}^{\prime }}^{\mathrm{\Phi }\mathrm{\Phi }}$ and (b) ${\stackrel{\rightharpoonup }{\stackrel{\rightharpoonup }{D}}}_{ij}^{RR}$ and the entire ${\stackrel{\rightharpoonup }{\stackrel{\rightharpoonup }{D}}}_{ik}^{\mathrm{\Phi }R}$ matrix [(c)–(d)] at 1 and 10ns displaying the decrease of all three types of correlations during the expansion of free RNA aqueous solution. This suggests large-scale motions of the system become less coordinated with time.
