Neutron-scattering measurements of wave-vector-dependent hydrogen density of states in liquid water

Light and neutron scattering studies of the OH stretching band in liquid and supercritical water

“…4 for the runs # 1, 2, 3, 4, 7: Also in this figure 2 2 , 1 and 3 , in the case of an isolated water molecule, are indicated by three vertical lines. We notice that the room temperature data are in excellent agreement with a previous experiment 12,13 performed using the HERMECS chopper spectrometer installed at the IPNS facility ͑Argonne National Laboratories, FIG. 2.…”

“…On the other hand inelastic neutron scattering studies in the same energy region have become feasible since the 80s, with the advent of spallation neutron sources, 11 and only the spectra of the normal and supercooled phases of H 2 O and D 2 O have been studied. 12,13 In the present paper we report a study of the O-H stretching spectra of water obtained by inelastic scattering of both light and neutrons, over a wide thermodynamic range, including supercritical states, as the comparison between these two techniques can shed some light over the interpretation of the complex Raman spectral shapes.…”

The O–H stretching band in ice Ih derived via eV neutron spectroscopy on VESUVIO using the new very low angle detector bank

“…The latter is not far from E. PERELLI-CIPPO et al O-H stretching in ice using the new VLAD unity and was estimated from its q → 0 limit [18]:…”

X-ray and Neutron Scattering of Water

“…This latter band shifts to a lower energy value of 217 meV in supercooled water, due to the formation of a more stable hydrogen bond network between neighboring molecules which makes a softer intramolecular attractive bond 158 . In the spectra also two bumps at 280 meV and 520 meV appear, which are the combination bands between the bending and the librational modes and between the stretching and the librational modes, respectively 142 . It is worth of note that both the position and the intensity of the bending and the stretching vibrational modes are quite sensitive to structural changes, confinement or interaction with polar groups.…”
