FIGURE 11.

(A) Amplitude of motions (jump distance d and radius of sphere a) involved in slow relaxation process at different hydration levels obtained from the fit to two-site jump model (▴) and to freely diffusive motions in a sphere model (▪). The dashed line shows the jump distance expected for methyl groups. (B) Variation of mobile fraction of hydrogen atoms involved in the slow relaxation process, P_slow, with hydration obtained from the fit to two-site jump model (▴, outside labels) and to freely diffusive motions in a sphere model (□, inside labels). QES intensity integrated in the frequency range from 2 to 8 GHz (○) is presented for a comparison.
