Abstract
We carry out a Nuclear Magnetic Resonance (NMR) spectroscopy study on the dynamics of lysozyme hydration water. We consider a hydration level corresponding to a single water monolayer. We investigate the thermodynamical region from 295K to 355 K, at temperatures below and above the “magic” temperature T∗ ≈ 320 K. In particular, we focus our attention on hydration water mean-square displacement (MSD) as a function of the diffusion time at different temperatures. Our results suggest the occurrence of a smooth anomalous diffusion from a sub-diffusive state (T < T ∗) to a super-diffusive one (T > T∗). These conclusions confirm the importance of the temperature T∗ as the border for water behavior.
