We measured quasielastic neutron spectra (0.2 Q −1 ) with a resolution of 13 μeV (HWHM) for 56% H 2 O-hydrated powder samples of the tripeptide glutathione, using a new pulsed-source backscattering instrument with considerable potential for advanc

Efficient exploitation of substantial increases in data volumes from third-generation pulsed sources requires a freely accessible database of neutron spectra from biomolecules and their building blocks. The main characteristics of existing biodynamic

Using a neutron backscattering spectrometer, the temperature dependence of mean-square atomic displacements derived from window-integrated quasielastic spectra was measured for two D2O-hydrated proteins: crambin and glutathione S-transferase. Analyse

Neutron Compton scattering (NCS) can be applied to measuring nuclear momentum distributions and potential parameters in molecules of biophysical interest. We discuss the analysis of NCS spectra from peptide models, focusing on the characterisation of

Third-generation neutron facilities are expected to provide the flux levels and dedicated instruments needed to exploit more fully the rich information content of energy-resolved neutron scattering from biomolecular systems. This paper reviews applic

We investigated molecular motions in the 0.3–350 ps time range of D2O-hydrated bilayers of 1-palmitoyl-oleoyl-sn-glycero-phosphocholine and 1,2-dimyristoyl-sn-glycero-phosphocholine in the liquid phase by quasielastic neutron scattering. Model anal

Neutron time-of-flight spectra for two hydrated disaccharides at 300 K show significant differences with respect to (i) discrete features in the 10 to 70 meV region, and (ii) a broad low-frequency band centred on 5.5-6 meV. We analysed these in terms

By covering the inelastic scattering region from ≈0.005 to 50 eV, neutron spectrometers at third-generation pulsed sources will be able to provide much new information on the dynamics of protons and protonated groups in peptides. Joint analyses of
