摘要：
Inelastic neutron scattering (INS) on pure water and on aqueous solutions of homologous disaccharides, such as trehalose and sucrose, are presented. Neutron spectra were collected by using the spectrometer MARI at the ISIS pulsed neutron source of the Rutheford Appleton Laboratory (Chilton, UK). The MARI spectrometer allowed us to get information on the hydrogen bond structural network in homologous disaccharide-water solutions by analysing the structural modifications induced by the presence of trehalose and sucrose on the main spectral features of pure water. Special emphasis was addressed to the intramolecular OH stretching mode. (C) 2004 Elsevier B.V. All rights reserved.
