摘要
Some preliminary results are reported concerning the dynamics of hydration water on the surface of myoglobin, investigated by incoherent quasi-elastic neutron scattering. Several samples of protein were studied at a water content of h = 0.1, 0.4 and 0.8 g/g. A lineshape analysis of the spectra provided the half-width and the elastic incoherent structure factor for the water contribution in the scattered intensity. At very low hydration, water molecules seemed to perform only rotational motion, whereas at greater hydration a diffusional motion, inside confined regions of about 6, took place.
