Analysis of the internal motions that result in lower order parameters for the cytosine ribose moieties. Orientations of the C1′–H1′, C3′–H3′ and C6–H6 vector of residue C3 (a) and residue C9 (b) in polar coordinates relative to the diffusion tensor (θ in black; ϕ in grey) along the last 14.5 ns of the trajectory. The ribose pucker phase (P, in black) and torsion angle χ (in grey) are also shown.
