Inelastic neutron scattering of perdeuterated cellulose

ORAL

Abstract

Perdeuterated cellulose has been prepared by feeding acetobacters with deuterated glycerol, and measured inelastic neutron scattering with planar orientation to obtain the elastic tensor. Perdeuteration allows for the measurement of anisotropic inelastic scattering spectra with low background compared to the hydrogenated one, which has high incoherent scattering depriving of structural information. Acoustic branch is observed around elastic line of 2 0 0 reflection, perpendicular to the pyranose ring, whereas not along the chain direction. The data are analyzed and discussed in the context of intrinsic structure factors of natural cellulosic material as well as the constraints in specimen preparation and measurement techniques.
