Abstract:
Polarised Raman micrsospectroscopy was employed to study the molecular structure within dislocations (slip planes) in the cell walls of Hemp fibre cells (Cannabis sativa (L.)). It was found that the cellulose microfibrils within dislocations have a different orientation than in the surrounding cell wall, and that the cellulose in the transition zones between a large dislocation and the surrounding wall may have yet another orientation. Furthermore, cellulose orientation seemed to be less uniform within dislocations than in the surrounding cell wall.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
